- 0:00From Yellowstone National Park, where elk bugles
- 0:02are starting to be the soundtrack to the mornings
- 0:04and evenings, this is that Scott guy you know
- 0:07and love with a brand new episode of This Week
- 0:10in Yellowstone. What's up everybody, this week
- 0:22in Yellowstone National Park from August 27th
- 0:25to September 2nd, 2026. I'll let you know what
- 0:29to actually expect when visiting the park in
- 0:31September, talk a bit about the importance of
- 0:33obsidian in the park, tell you what is closing
- 0:36in the park this week, and try to explain why
- 0:39seeing a grizzly this time of year is so hard
- 0:41to do. I'll also give you the complete weather
- 0:43forecast, a cool trail to hike, the wildlife
- 0:46report, and everything else you need to have
- 0:49an incredible time. this week in Yellowstone.
- 0:52My standard disclaimer, I may miss a few details
- 0:54here and there. And I also mentioned park locations
- 0:57very casually. So if you're unfamiliar with a
- 1:00place I'm talking about, a quick search online
- 1:02can help or just reach out to me. You can email

- 1:46contact me directly. The Outdoor Society at gmail
- 1:49.com or 406 -589 -1873 for texts. This week's
- 1:56Yellowstone news. So there's not a lot going
- 1:58on in the park newsworthy wise, which is always
- 2:00good. I'm always happy not to have much to talk
- 2:03about. There has been a video circulating in
- 2:06social media of a person hiking out. It looks
- 2:10like Lamar Valley and there was a single wolf
- 2:13following them and the guy hiking sprayed some
- 2:17bear spray at the wolf to try and get to go away.
- 2:19There's been a lot of like conjecture of, well,
- 2:21that guy shouldn't have been out there hiking.
- 2:24And then some of it's like, well, there's a trail
- 2:26out there or there's not a trail out there. I've
- 2:28said this before, and I'll say it again. If there's
- 2:31an area you're not allowed to go to, the park
- 2:33will put up plenty of signs and make sure people
- 2:36don't go there. Currently, the only places you
- 2:39can't go are closed trails, which are on the
- 2:42backcountry situation report, and I have a link
- 2:44to that in the show notes. The thermal areas,
- 2:47you can't go off trail there or you can't go
- 2:50off trail and bear management areas. Other than
- 2:52that, you can walk where you want. So I know
- 2:56a lot of people don't want people walking out
- 2:58where there's a potential for wildlife, but there's
- 3:01a potential for wildlife everywhere in the park.
- 3:03I was talking about this the other day. I've
- 3:05seen grizzly bears on the boardwalks. I've seen
- 3:08bison on the boardwalks. You know, there's animals
- 3:11all over the park. And just because there's a
- 3:14trail there doesn't mean that the animals aren't
- 3:15going to be there. I know a lot of people will
- 3:18see something like that and think, oh, that shouldn't
- 3:20have happened. Incidents with wildlife happens.
- 3:23It looks like all went well from what I've heard
- 3:25It was an experienced hiker in Yellowstone did
- 3:27everything right nothing bad happened. That's
- 3:30the end of that So just wanted to mention it
- 3:32briefly in case you saw it on social media. It's
- 3:34not really a news story man encounters wolf while
- 3:38hiking in Yellowstone is not like The most amazing
- 3:42thing you're ever gonna hear from the park. It
- 3:43happens all the time I've had tours where we
- 3:46encounter wolves in the backcountry. It just
- 3:47happens and it looks like everything happened
- 3:50that wolf learned a lesson that don't approach
- 3:52people which is good because we don't want wolves
- 3:54to be habituated that's a whole other conversation
- 3:57we'll probably get into in the fall or winter
- 3:59but for now if you see that video know that just
- 4:02like that bison video of that guy getting tossed
- 4:05everybody involved did everything correctly sometimes
- 4:08things just happen in this one no one got hurt
- 4:11no animal got hurt and that was that The other
- 4:15news thing I want to talk about is that this
- 4:17is really the last week I mentioned it off the
- 4:19top. This is really the last week for everything
- 4:22in the park to be open. Next week, things really
- 4:26start to close and they close every single week
- 4:28more and more things. This is the last week in
- 4:31the park that you can do horseback and stagecoach
- 4:33rides. Also the dining room at Roosevelt the
- 4:38Roosevelt store is going to be closing on the
- 4:40seventh Tower Roosevelt gas station the inside
- 4:43of it closed on the six There are some other
- 4:45things that are closing right now like repair
- 4:47shops and things like that But I generally don't
- 4:50cover that anyway, but I want you to know this
- 4:52is really that last week The last full week of
- 4:55everything that's open in the park being open
- 4:58And then we're just going to watch it kind of
- 5:00close off. So be aware of that for next week.
- 5:03This week, enjoy what's open. If you're on the
- 5:05fence about booking one of those horseback tours
- 5:07or stagecoach rides or cookout dinners out of
- 5:10Roosevelt, recommend doing it. It's a unique
- 5:13experience. And when else can you do that? Right.
- 5:15So enjoy that. That's really all the news. So
- 5:18we are going to jump right in to the experience
- 5:22of the week. Apologies for the stutter there
- 5:25or the delay. I've done this so many times and
- 5:28then I forget what comes next, even though I
- 5:30have my template right in front of me. So my
- 5:33experience of the week is do not expect September
- 5:36to be empty in the park. There's this myth going
- 5:40around. I talk about it every year. I've talked
- 5:42about it the last decade or so on my website,
- 5:45and now I talk about it on the podcast. But there's
- 5:48this myth that once the kids are back in school,
- 5:50the parks are empty. This is false. This is fundamentally
- 5:54false on every single level. September in Yellowstone
- 5:58National Park gets about 94 to 97 % of the visitation
- 6:02that it gets in August. I'll say that again.
- 6:0694 to 97 % of the visitation of September compared
- 6:10to August. That means if August had a million
- 6:13people, that'd be 940 ,000 to 970 ,000 people
- 6:17in the park. And that is a lot of people. You
- 6:20will have over 800, probably over 900 ,000 people
- 6:24this September in the park. Those are facts.
- 6:26It doesn't mean that it's not going to be fun
- 6:28to visit. I just really have to make sure that
- 6:31if you're visiting that you know that that's
- 6:33going to happen. Obviously, it does feel less
- 6:37crowded because the people that are visiting
- 6:40are usually a different age and a different speed.
- 6:43People going back to school is real. However,
- 6:47we have a larger retiree work from home population
- 6:52than we've ever had. So everybody that wants
- 6:54to avoid the summer when all the kids are there
- 6:56is now coming in the shoulder season. I like
- 6:59to study statistics. If you know me at all, you
- 7:02know I could talk about this forever. I'm not
- 7:03going to talk about numbers right now, but September
- 7:07is a popular month. Because like I just said,
- 7:11it's a good shoulder season month the elk ruts
- 7:13going on Everything's a little cooler animals
- 7:17are starting to be more active when they were
- 7:19more lethargic in the summer there's a sense
- 7:22of like urgency for all the animals too because
- 7:25winter is coming and That's not just a Game of
- 7:29Thrones reference, it is winter is coming and
- 7:31winter is very harsh here, so everything needs
- 7:33to get ready. September is when we start seeing
- 7:35bears really start eating for hyperphasia to
- 7:39just pack on the pounds to get through winter.
- 7:41As I mentioned, the elk rut is going to start
- 7:44popping off any day now, and it's an exciting
- 7:47time to be in the park. Fall colors hit, daylight
- 7:51hours shortened dramatically. There's a crispness
- 7:54in the air. September may see the first snow
- 7:56in the mountains. It's a great time, but it's
- 7:59not going to be an empty time. And I know that
- 8:03like everything you may read will say it's going
- 8:06to be much less crowded. That's still October.
- 8:09October, though, is still growing. I'll talk
- 8:11about that at the end of September. But right
- 8:13now, if you come in September to the park, here's
- 8:16what to expect. The popular areas will be crowded.
- 8:20Wildlife jams will occur. The lesser known spots
- 8:24will be empty. Wildlife watching will be amazing.
- 8:28The rivers will be really pretty. The stars are
- 8:31going to be gorgeous. It's going to be super
- 8:33awesome to go to. Like I love September. It's
- 8:37one of those months that I usually take off from
- 8:39guiding because I love going out in September
- 8:42so much. If you're a hiker, September is the
- 8:44time to visit. You have cool mornings, your highs
- 8:47maybe get in the 70s, but probably not. You're
- 8:51just going to be able to hike in a sun shirt
- 8:53and roam around in mostly snow -free trails.
- 8:56Yes, you're going to have to be very bear -aware,
- 8:59but if you're hiking in Yellowstone, you should
- 9:00always be very bear -aware. If you noticed me
- 9:03just over -enunciate, I had to record that three
- 9:05times because the first time I did it, I said,
- 9:08be very bear -a -bear. And that's not, that's
- 9:11nothing, but be very bear -aware. This is the
- 9:16time, especially if you're going up in the high
- 9:17country. I really like to do long days in the
- 9:20mountains right now. The rivers and creeks are
- 9:22low if you need to forward them. It is a fantastic
- 9:25time for trails. If you're visiting in September
- 9:27or early October and we don't get a lot of snow,
- 9:30message me. I will tell you where I'd be hiking
- 9:32right now and hopefully you go there because
- 9:35it's truly fantastic. I mentioned that the areas
- 9:37that are popular are crowded and that's going
- 9:39to be the case. But with the shortened daylight
- 9:43hours, You're going to see crowds disperse even
- 9:47faster in the afternoon and get there kind of,
- 9:50you know, later in the morning because sunrise
- 9:52isn't as early. So you can really plan your time
- 9:54around decent hours. You don't have to stay out
- 9:57in June and July. You kind of have to stay out
- 9:59for sunset until nine thirty, nine forty five
- 10:02now. Sunset's around eight fifteen. And that's
- 10:06great because you can watch sunset at the lake
- 10:08at eight fifteen and you can drive back out to
- 10:10West Yellowstone. You're there, you know, nine
- 10:12thirty. maybe 10 depending on what's there. Yes,
- 10:15it's going to be dark to drive through the park,
- 10:16but you know, if you visit, you know you kind
- 10:19of have to do that to do the things. The fall
- 10:21colors in September in Yellowstone are going
- 10:24to be muted for what a lot of people expect.
- 10:27The better fall colors in this region will be
- 10:30down in the Tetons. I will admit that the fall
- 10:33colors in the park in Yellowstone are great,
- 10:35but the Tetons are really where it's at. Usually
- 10:38this time of the year, September, early October
- 10:40is when I take my yearly trip to the Tetons to
- 10:43see the fall colors, to see the moose mating,
- 10:45all of those things. If you're in the area, recommend
- 10:48doing that. But the fall colors here, these colder
- 10:51nights that we have really start getting the
- 10:54reds and the oranges on some of the underbrush
- 10:56to be really beautiful. The fireweed right now
- 10:59has some cotton blowing around off of it. It's
- 11:02a really pretty time. Hillsides are starting
- 11:03to erupt in some red from all of the plants there.
- 11:06It's pretty, but don't expect a lot of, you know,
- 11:09leafy trees to be turning. We do have Aspen,
- 11:13and those Aspen will be turning gold. And then
- 11:15you can just sit under them with a white bark
- 11:17and listen to the golden leaves rustle in the
- 11:19wind. If it's blue sky, it's like the most picturesque,
- 11:23wonderful thing. I love it. And that's why you
- 11:26come in September. You get those moments. The
- 11:29picnic areas will be less crowded than in the
- 11:31summer. You will have less people and it's a
- 11:33different type of person in the park. That's
- 11:36not a judgment statement. That's just a fact.
- 11:38You're going to have older people. You're going
- 11:40to have younger people that are in camper vans
- 11:42instead of families that are going to need to
- 11:45do more activities. People will really plan to
- 11:48be much slower in the park. And that's where
- 11:51this idea that the park isn't as crowded comes
- 11:53in. You get a lot less people rushing to and
- 11:56fro trying to see everything. And you get a more
- 11:59experienced Yellowstone National Park crowd at
- 12:02most places. You still have first time visitors
- 12:04and as you should. But I've noticed that a lot
- 12:07of people that come in September really know
- 12:09the park. And so their experience are. is a lot
- 12:12more like, OK, yeah, maybe we'll go see Old Faithful
- 12:15once and then we want to go to our favorite spot
- 12:18out here or we want to go post up at a pullout
- 12:20in Lamar for the next four hours or we're going
- 12:23to do a hike because we love this hike this time
- 12:25of year. It's a different group of people coming
- 12:27in. Every season is a little different. So September
- 12:30is going to have that. You will have some traffic
- 12:32jams at West Yellowstone. That's going to happen.
- 12:34You're going to have parking issues at Grand
- 12:36Prismatic Overlook at some of the more popular.
- 12:39geyser basins you're gonna have bison that are
- 12:42gonna snarl traffic you're gonna have elk if
- 12:45there's a bull elk around you're gonna have people
- 12:47just losing their minds next week is my elk special
- 12:51it's a regular episode it's not gonna be a standalone
- 12:53bison episode like i did but i'm gonna primarily
- 12:56be talking about the elk rut and things like
- 12:58that so wait for that for next week but know
- 13:01that if there is a bull elk around It's a bit
- 13:04of a madhouse no matter where you are, whether
- 13:06you're in Mammoth, you're in Madison, you're
- 13:09at the lake. There's a bull elk bugling and he's
- 13:12trying to get his harem together. You will see
- 13:15the craziness of September visitation and every
- 13:17month has craziness because it's Yellowstone
- 13:19and people are excited and I love that they're
- 13:22excited. Just make sure you follow the rules
- 13:23and we all can enjoy this. The other thing I
- 13:26wanted to talk about September is things will
- 13:29close. Plan ahead with that some restaurants
- 13:33will close if they didn't get enough seasonal
- 13:35workers in West Yellowstone or Cook City or Gardiner
- 13:38Then they may have reduced hours That is a very
- 13:41important thing to know because if you expect
- 13:43things to be open late in the shoulder seasons
- 13:46You will be disappointed and you might have to
- 13:48get food at a gas station I've done that when
- 13:51I visited years ago. I had some friends visit
- 13:54the other year and they mistimed it and They
- 13:57ate just gas station sandwiches for dinner and
- 14:00it was fine you know but it's just because oops
- 14:03we stayed out too long and then everything was
- 14:05closed so know that but otherwise if you're visiting
- 14:08in september just know it's not going to be completely
- 14:10empty but also know that september is so magical
- 14:14and so wonderful i love it i am Truly stoked
- 14:17that September is here. I mean, yes summer went
- 14:20way too fast for me, but September's here You're
- 14:23gonna probably hear about me doing super long
- 14:25days on the trails wildlife watching is gonna
- 14:28increase We're gonna have bears just eating tons.
- 14:31You have elk bugling. You're gonna have Marmots
- 14:35and pikas gathering as much food as they can
- 14:37for the winter. You're gonna get the migratory
- 14:40birds gathering together Before they leave in
- 14:42October the end of September. It's a good time
- 14:45to visit If you are visiting, be very excited.
- 14:48Just know you may not be alone all the time.
- 14:52All right, that was my unscripted section. Now
- 14:55I'm going to have my tip of the week. Why are
- 14:59grizzly bears so hard to find in late August?
- 15:02Oh, all of August. So if you're in Yellowstone
- 15:05at the end of August, middle of August, early
- 15:08August, and you're hoping to see a grizzly bear
- 15:11from the road, it helps to understand one thing.
- 15:14The bears are around, but they're not going to
- 15:17be where they were in May and June and some of
- 15:20July. Mid to late August is an interesting transition
- 15:24point for Yellowstone's bears. Summer's winding
- 15:27down, fall's approaching, and the animals are
- 15:30spending much of their time looking for the most
- 15:32nutritious foods they can find. Where those foods
- 15:35are located can have a much bigger influence
- 15:37on where you'll find the bears throughout the
- 15:40park. For grizzly bears especially, Late summer
- 15:43is a period of intense feeding. From June through
- 15:46August, grizzlies eat a wide range of foods including
- 15:49grasses and sedges, thistle, fireweed, biscuit
- 15:52root, ants, army cutworm moths, all of these
- 15:56things. But by midsummer, they also then start
- 16:00honing in on berries. This time of the year,
- 16:04even a few weeks ago, this is the time of the
- 16:06year when the berries start popping out and the
- 16:09bears will go crazy for them. One place I usually
- 16:12see some black bears this time of the year is
- 16:14the Slough Creek Trail, especially those first
- 16:15one to two miles. I've had them right next to
- 16:18the trail and I've just basically shut the trail
- 16:20down and didn't let anybody hike it because there
- 16:22were three black bears just hanging out right
- 16:24by the trail and it's not safe to walk by them
- 16:26when they're eating. Now, we're not talking about
- 16:29blackberries, though. Most people that have reached
- 16:30out to me, by the way, this is a viewer -centric
- 16:33or listener -centric answer for a bunch of questions
- 16:38I've gotten about where to see grizzlies because
- 16:40people want to see grizzlies and grizzly sightings
- 16:43have been very minimal. And one of the reasons
- 16:45for that is because those grizzlies are really
- 16:49looking for very high calorie foods. And those
- 16:54are moths and whitebark pine seeds. These moths
- 17:01that they eat spend a lot of their time way high
- 17:04up this time of the year above 10 ,000 feet and
- 17:08grizzlies will climb to these areas and turn
- 17:10over rocks and feed on them just over and over
- 17:14again. The moths are extraordinarily extraordinarily
- 17:17nutritious and the National Park Service says
- 17:20that a bear can consume tens of thousands of
- 17:23these moths in a single day. One thing that you
- 17:27need to know is that there are not roads up to
- 17:29these 10 ,000 foot rocky areas. These are remote,
- 17:33and the bears are going to remote areas right
- 17:36now to eat. For a visitor driving Yellowstone's
- 17:39roads, that's not especially encouraging. A bear
- 17:42concentrating on moths right now in the high
- 17:45mountains, not going to be visible from roadside
- 17:47meadow, not even with spotting scopes or things
- 17:49like that. You're going to really have a hard
- 17:51time seeing them. Plain and simple. They're with
- 17:55the best food source. This is like if we all
- 17:57had this little diner that no one else knew about
- 18:00but we had to walk Way through the woods and
- 18:03like hide from everybody to go eat at this best
- 18:05diner in the world That's what these bears are
- 18:08doing. It's not that they want to keep it a secret
- 18:10It's just that that is where these moths are
- 18:12there's also whitebark pine needles up high there
- 18:16and so that's where they're going to be I I know
- 18:19it's a little frustrating but This is the reality
- 18:23of where grizzlies are and this is why it's important
- 18:25to understand this Migratory if you want to use
- 18:28that word for this pattern that the animals have
- 18:30where their food sources are I talked a lot last
- 18:33year about the whitebark pine and if you want
- 18:36to check that out I think is around this time
- 18:37of the year and so the bears are going up there
- 18:41and This is kind of fun because they go up there
- 18:44and they eat these seeds And it's nice, but one
- 18:47of the things that they love doing is finding
- 18:50the caches made by red squirrels and other little
- 18:52rodents and just eat what they've been storing
- 18:55for the winter. Now you may feel bad for them
- 18:58but squirrels and things like that are notorious
- 19:00for gathering a bunch of food and then forgetting
- 19:02about it. So this has been happening forever
- 19:04and this is how things survive. So the bears
- 19:07are moving up higher and that means it's going
- 19:09to be a lot harder to see. If you do things like
- 19:11the specimen ridge trail or you go up Mount Norris
- 19:14or even Mount Washburn you might have better
- 19:17luck up there. If you see a grizzly right now
- 19:22just next to the road in a valley it's because
- 19:24there's a good food source there. And if there's
- 19:26a good food source there, it's going to be there
- 19:28for a while. So if there is a bear nearby, it's
- 19:31not going to be roaming as far theoretically
- 19:33right now as much as it was in the height of
- 19:36the summer when it was just kind of roaming around
- 19:37and doing its bear thing. Right now, everything
- 19:40is locked in on where food is. The later in the
- 19:43season we get, the more narrow that focus gets
- 19:46on food sources. So if there's food around, they
- 19:49are very attentive to it. Now this may sound
- 19:52like a bummer, but this isn't to say that the
- 19:54valleys are empty of bears Or you're not going
- 19:56to see them quite the opposite Yellowstone's
- 19:59wildlife Goes everywhere and again, they go where
- 20:03those food sources are so you can go Tower Roosevelt
- 20:06to Canyon and Then in Hayden Lamar and you might
- 20:10see a grizzly bear if you go out toward the Beartooth
- 20:13Highway right now That's a high elevation area.
- 20:15There might be more grizzlies out there. I will
- 20:17be keeping track of where they are and trying
- 20:20to let you know when you're visiting. Right now
- 20:22you're just going to have to put in the miles
- 20:23like I always say in the wildlife report. The
- 20:26challenge for finding bears right now is that
- 20:29again they're just up high and there's not a
- 20:32lot of up high access in the park. The good news
- 20:35is that August is the hardest month for me and
- 20:39a lot of other people to see grizzlies in the
- 20:41park. Why is that good news? August is over as
- 20:46this podcast lasts the entire week, we're going
- 20:50to get into September. September is when you
- 20:52start seeing more black and grizzly bears on
- 20:54roadside meadows really feasting. So if you were
- 20:57in the park this last month, know that this was
- 20:59the hardest time late July through the month
- 21:01of August is the hardest time to see a grizzly
- 21:03bear. And so next time you come back to the park,
- 21:06you can know that and plan differently if you
- 21:09can. You know, you come to the park when you
- 21:11can and you see what you see. The park allows
- 21:14you to see what it allows you to see. And we
- 21:15can't really control that. So maybe you saw a
- 21:18grizzly. Maybe you didn't. But if you are coming
- 21:20this week, we're going to start getting to the
- 21:22point where, yes, grizzlies are up high, but
- 21:25they're also going to be locking in on some of
- 21:27those historic food ranges. So if bears are known
- 21:29to be a certain place. During September and October
- 21:33they're going to return to that place if there's
- 21:36a route in a field I'm thinking around the Grizzly
- 21:38Lake area. Maybe check out that area You know
- 21:42that there is a consistency to where they get
- 21:45their nutrition as long as it's still there so
- 21:48Listen to the wildlife report talk to people
- 21:51when you're visiting the park talk to the Rangers
- 21:52They can tell you where things are and if you
- 21:55visited in August and didn't see a grizzly bear.
- 21:57Don't worry I only saw one all year and it was
- 22:00way off on a hike and I saw it from three miles
- 22:02away on a ridge so I didn't really get a good
- 22:05grizzly sighting this August but I expect better
- 22:08sightings in September and September is right
- 22:11around the corner. My random Yellowstone fact
- 22:13of the week. Yellowstone's obsidian. Few rocks
- 22:17in Yellowstone National Park tell a more remarkable
- 22:19human story than obsidian. For thousands of years
- 22:23These rocks were one of the most valuable toolstones
- 22:26available to people living and traveling across
- 22:28the American West. Yellowstone's obsidian was
- 22:31quarried, shaped into razor -sharp tools, carried
- 22:35across enormous distances, and traded between
- 22:38communities. Archaeologists can now trace some
- 22:41of those ancient journeys, chemically, so, you
- 22:43know, looking at the rock, revealing that Yellowstone
- 22:46was connected to a continent -wide network of
- 22:48movement and exchange long before the arrival
- 22:51of Europeans. This is not a shock, the trade
- 22:53economy of the indigenous folks was amazing.
- 22:57Obsidian is a naturally occurring volcanic glass.
- 23:00It forms when silica -rich lava erupts and cools
- 23:02so quickly that crystals do not have time to
- 23:05develop. Instead of becoming a conventional crystalline
- 23:08rock, the molten material solidifies in a glass.
- 23:12The process requires both rapid cooling and magma
- 23:15with the right chemical composition. Yellowstone
- 23:18is particularly well suited to producing obsidian
- 23:21because of its volcanic history that has generated
- 23:24extensive rhyolite lava flows, which are rich
- 23:26in silica and highly viscous. That viscosity
- 23:30slows the movement of atoms needed to form crystals,
- 23:33helping preserve the glassy texture. One of the
- 23:36most spectacular examples is Obsidian Cliff.
- 23:39Located along the road between Mammoth and Norris,
- 23:42the cliff exposes an enormous obsidian -bearing
- 23:44rhyolite flow that erupted roughly 180 ,000 years
- 23:48ago. Unlike most obsidian deposits, which occur
- 23:52as scattered rock mixed with other geologic material,
- 23:55Obsidian Cliff forms a massive exposed cliff
- 23:58approximately 98 feet or 30 meters thick. The
- 24:02site was designated a National Historic Landmark
- 24:04in 1996 because of both its geologic importance
- 24:08and its extraordinary archaeological significance.
- 24:12The qualities that make obsidian fascinating
- 24:15to geologists also made it extraordinary for
- 24:18humans. When obsidian breaks it produces what
- 24:21is called a Concodial fracture. I probably said
- 24:26that wrong. That creates thin curve flakes with
- 24:29extremely sharp edges. Skilled toolmakers could
- 24:32strike a piece of obsidian and remove precisely
- 24:36shaped flakes, producing knives, scrapers, spear
- 24:39points, arrowheads, and other cutting tools.
- 24:43So people began quarrying obsidian at Obsidian
- 24:45Cliff more than 11 ,000 years ago. Archaeological
- 24:49investigations have identified quarry pits, workshops,
- 24:52flakes, cores, and finished tools, showing that
- 24:54people were not simply picking up a few attractive
- 24:57pieces from the surface, they were deliberately
- 24:59seeking out material and processing it at the
- 25:03source. Obsidian from obsidian cliff became one
- 25:06of the most widely dispersed obsidian sources
- 25:08used by hunter -gatherers in what is now the
- 25:10entire United States. So this little area in
- 25:14Yellowstone National Park that you drive through
- 25:16just south of Mammoth, which is largely overlooked
- 25:19by everyone visiting the park, is one of the
- 25:21most historically significant obsidian places
- 25:24in the United States, if not North America. But
- 25:28it's not just there. Yellowstone isn't limited
- 25:30to just a single obsidian source. Archaeologists
- 25:34have identified at least 16 prehistoric obsidian
- 25:37sources within the greater Yellowstone ecosystem.
- 25:40including locations like Cougar Creek, Park Point,
- 25:44Conan Creek, and other areas around the park
- 25:46and surrounding region. Different communities
- 25:48could therefore obtain obsidian from sources
- 25:50closer to where they are traveling, but obsidian
- 25:53cliff became especially important because of
- 25:55the quality and abundance of material. So you
- 25:58may be wondering, how do they know that obsidian
- 26:00came from obsidian cliff? And that's because
- 26:03obsidian has a chemical fingerprint. There's
- 26:07trace elements within obsidian that vary from
- 26:09one source to another. Scientists can analyze
- 26:13an archaeological artifact and compare its chemical
- 26:16composition with known geological sources. This
- 26:19allows researchers to determine where a particular
- 26:22piece of obsidian originated without destroying
- 26:24the artifact. In effect, the rock carries a geologic
- 26:28signature that can reveal where it came from.
- 26:30These fingerprints have revealed just how far
- 26:33Yellowstone Obsidian traveled. Material from
- 26:35Obsidian Cliff has been identified at archaeological
- 26:37sites throughout the Rocky Mountains and Great
- 26:39Plains, and as far north as western Canada, and
- 26:42as far east as the Great Lakes and Ohio. The
- 26:46obsidian in this region also can help provide
- 26:49a window into the earliest chapters of Yellowstone's
- 26:52human history. One Clovis point found near present
- 26:55-day Corwin Springs just north of the park was
- 26:58made from obsidian cliff obsidian and dates to
- 27:01around 11 ,000 years old This discovery demonstrates
- 27:07that people were not only present in this region,
- 27:10but they were also Recognizing what was useful
- 27:13very established and setting things up I wanted
- 27:16to talk about Obsidian Cliff because it doesn't
- 27:19get as much love as I feel it should for how
- 27:21important it is. Yellowstone has so many awesome
- 27:24places, so many places where you're just like,
- 27:28your mind is blown. Obsidian Cliff is very subtle.
- 27:30you'll drive by it you might see the little kiosk
- 27:35on the side and very small parking area that
- 27:38kiosk is part of the national historic on the
- 27:40national historic registry by the way that's
- 27:42a fun little fact that no one really cares about
- 27:44but i read that the other day and i like to share
- 27:47it every chance i get but obsidian cliff shows
- 27:51the importance of yellowstone and it also shows
- 27:54how important yellowstone has been for humanity
- 27:57since day one in this area I love obsidian cliff.
- 28:01Next time you drive through, stop, read the little
- 28:03display, look at the cliffside, and know that
- 28:07while it's not the most impressive and jaw -dropping
- 28:10thing, this easy -to -miss roadside stop is one
- 28:16of the most important pieces in hunter -gatherer
- 28:19history in America. So I wanted to mention that
- 28:22this week. Now let's talk about the weather.
- 28:25Alright the weather for the coming week as always
- 28:27this is the best forecast at the time of the

- 31:25of rain and Wednesday 65 and 42 19 percent chance
- 31:30of rain by the way that Sunday that Saturday
- 31:34and Sunday low It might snow in the Beartooth
- 31:36Highway. So do not be surprised if the Beartooth
- 31:39Highway closes Sunday, maybe Saturday as well
- 31:42It may not this forecast could just be tossed
- 31:45out the window in like two hours. But as of right
- 31:48now Could happen. As of right now, no major roads
- 31:51are closed in the park. Those dirt roads like
- 31:53the Blacktail Plateau Drive will be closed if
- 31:56it rains. Know that there's going to be some
- 31:58construction here and there that's going to delay
- 32:00you. It hasn't been too bad at all. And, you
- 32:03know, if the weather does get bad and it snows.
- 32:05There might be some temporary road closures.
- 32:08We'll see it. This is a weird time of the year,
- 32:11so we're just going to see if it happens. It
- 32:13happens. If it doesn't, it doesn't. But if you
- 32:16want up to date road information, you can call
- 32:17307 -344 -2117 for recorded information, or you
- 32:22can do what we all do out here. Just sign up
- 32:25and receive Yellowstone road alerts on your cell
- 32:27phone by texting the number 82190 to the number
- 32:31888 -777. Camping information. Everything that's
- 32:36open this year is open this year. So if you're
- 32:39camping, have fun, might be what? The Wildlife
- 32:42Watching Report. So as you heard me talk about
- 32:46earlier, wildlife watching is hit and miss right
- 32:48now. The bison rut is winding down. I saw somebody
- 32:52posting that the bison rut's over. It's not true.
- 32:54Bison Red is not over. I was there yesterday
- 32:57and bison were running around. They were doing
- 33:00the lip curls after females. They were battling
- 33:04each other. Bison Red is not over. Bison have
- 33:08been better in Hayden Valley than they were the
- 33:11previous few weeks, so that's good. They've also
- 33:13been really prevalent in Little America and the
- 33:16Lamar Valley. I saw so many right next to the
- 33:20road driving to Lamar Valley yesterday. So if
- 33:22you want good bison sightings That's where I'd
- 33:24personally go Hayden can be hit and miss but
- 33:27if they're there they're gonna be there right
- 33:29on the road So enjoy that the elk rut is starting
- 33:33The question mark with starting the elk are starting
- 33:38to gather where they normally gather. So right
- 33:40now there's more elk and mammoth The big bull
- 33:43elk number 24 is back in Mammoth. I'm going to
- 33:46be talking about him next week, specifically
- 33:49him next week. So that should be hopefully interesting.
- 33:53I'll also be talking about the elk more as it's
- 33:55actually going to be popping off. But right now,
- 33:58don't be surprised to start hearing some bugles.
- 34:00to start seeing more bull elk emerging. They've
- 34:03scraped off some of the most of that velvet.
- 34:05They are looking good and they are ready to battle
- 34:08and mate and get their harems going. So Madison
- 34:11River Valley around the lake should be good,
- 34:14too. And then definitely Mammoth Gardner. That
- 34:18whole area that's always really good will have
- 34:20elk. I drove through yesterday and I saw about
- 34:2345 elk and mammoth. So I. I expect that to continue,
- 34:28but they could roam around. They do that. They're
- 34:30animals. So know that. And then let's see. Bighorn
- 34:34sheep have been few and far between as of late.
- 34:37So that's been a little disappointing. I've heard
- 34:39they've been pretty good up Chittenden Road by
- 34:43Mount Washburn and then also out the East entrance.
- 34:46They've just been roaming around closer to the
- 34:48East entrance side of the pass than the park
- 34:50side of the pass, if that helps. then wolves
- 34:53have been spotted out in Lamar in that general
- 34:56area quite a bit they've been far out there was
- 34:58a dead bison that grizzlies were eating or a
- 35:01grizzly was eating and wolves were kind of harassing
- 35:04them a week or two ago so that could continue
- 35:07to happen I would head out that way and then
- 35:10just see what's going on people have been seeing
- 35:12them from the force wolves from the forces of
- 35:14nature trail as well not as frequent as like
- 35:18a month ago but Then I'd also go down to Hayden
- 35:21and look for the wolves down there. Those are
- 35:23going to be your three main spots. And then bears
- 35:26are just going to pop up. You know, I wish I
- 35:29had a better solution, but as I talked about
- 35:30with bears, just a hard time for bears. I've
- 35:33seen more bears within three miles of Livingston,
- 35:35Montana than I have in the park in the last week.
- 35:39Now that's they're all black bears, but I've
- 35:42seen more bears. I haven't seen a black bear
- 35:44in the park in quite a while. So I don't really
- 35:47know what to tell you. It may change overnight,
- 35:50especially this cooler weather that's going to
- 35:52force some things to move. So expect maybe bear
- 35:54sightings to pick up later in the weekend. Other
- 35:58than that, pronghorn are starting to gather a
- 36:00little more. And then I've seen more deer driving
- 36:04between mammoth and Roosevelt than I ever have.
- 36:07Some good bucks are out there as well. And then
- 36:11Sandhill cranes are. all over, been seeing some
- 36:14cool eagles and ospreys, so it's a good time.
- 36:17These cooler temperatures may reduce visibility
- 36:19and you may not be able to scan as much, but
- 36:21again, you put in the miles, you put in the work,
- 36:23you may be rewarded with really good animal sightings.
- 36:26If you need more animal sightings, I have a wildlife
- 36:28watching guidebook. It's pretty good. If I say
- 36:31so myself, I'm not one to brag, but it's based
- 36:34on my entire life visiting the park. And while
- 36:38animals aren't predictable, they do have some
- 36:40tendencies that are repeated. And I share those
- 36:43and I really try and give you all of the knowledge
- 36:45that I have so you can have your best chance
- 36:47of seeing wildlife. Trail alerts and updates.
- 36:51So I just pulled up the backcountry conditions
- 36:53page last week. I threw something in the show
- 36:56notes that I didn't mention that a big trail
- 36:58was closed. Does not appear to be closed anymore.
- 37:02So that's good. There is a carcass way out way
- 37:07beyond where people are going to be day hiking
- 37:09on Cache Creek specimen, not specimen ridge,
- 37:13but Lamar Valley, lower Cache Creek area. I.
- 37:18heard about it there's a lot of grizzly prints
- 37:19out that way there wolf prints out that way too
- 37:22so you know be very alert it's a time that i
- 37:26think a lot of people are like oh it's a little
- 37:27more laid back wildlife wise because of things
- 37:29like i said but bears can be everywhere if there's
- 37:33a food source there they will be protecting it
- 37:35so be alert carry bear spray don't have it in
- 37:37the bottom of your backpack know how to use it
- 37:40and have it ready to be deployed in one to two
- 37:41seconds and finally my trek of the week The Specimen
- 37:46Ridge Petrified Forest Trail. If you love short,
- 37:49steep hikes with a big payoff, this is the hike
- 37:52you'll want to put on your Yellowstone list for
- 37:54this week. Now, I will say that if it's raining,
- 37:57this trail can be muddy, the views aren't going
- 37:59to be as good, but if it's not raining and the
- 38:01storm's passed and you feel like dealing with
- 38:03mud, or if it's not muddy at all, definitely
- 38:06go up here. It's short -ish, it's steep, and
- 38:10it gives you a stunning view and some really
- 38:12cool geology. What makes this great is you get
- 38:15to see petrified trees up close, not in a cage
- 38:19like the one at the petrified tree parking area.
- 38:22You get to see them on a hillside with sweeping
- 38:25views and you get to touch them. Don't take them,
- 38:28don't chip anything off, leave them the way you
- 38:30found them. But you get to have a tactile experience
- 38:33on a really cool trail. Now petrified wood that
- 38:37you're going to find here is roughly 50 million
- 38:39years old and dates back to when Yellowstone
- 38:42looked dramatically different than it does today.
- 38:44Ancient volcanoes that you're going to be looking
- 38:46at if you climb up it to the north and northeast
- 38:49were active and covered this part of the park
- 38:52which wasn't a park obviously then with ash rock
- 38:56and mud and over millions of years the mineral
- 38:59rich mud and all of that moved through the wood
- 39:02and replaced it and turned it into stone and
- 39:06it's really cool. The original wood disappeared
- 39:09and it just left behind remarkably detailed stone
- 39:12replicas of the trees. You can look at some of
- 39:15these pieces and you can see the rings of the
- 39:18trees in rock. Now before I describe the route
- 39:20to get there I want to share Yellowstone National
- 39:23Park's basic directions because this is not a
- 39:26traditional well -marked trail. From the pullout,
- 39:29look southwest away from the road. Toward the
- 39:32top of the ridge, around the 2 o 'clock position,
- 39:34you should be able to see a cliff outcropped
- 39:36containing petrified trees. The outcrop is your
- 39:39ultimate destination. From the pullout, follow
- 39:41the abandoned service road for about 100 yards,
- 39:44then ignore the boot path on the left and keep
- 39:47going up the ridge. Continue on the most obvious
- 39:50trail to the top of the open ridge, then follow
- 39:52the ridge southwest toward the cliff outcrop.
- 39:56There are wildlife trails that traverse the forest
- 39:58below the ridge but these can lead you off the
- 40:00route so stay on the main path and avoid following
- 40:03animal trails into lower terrain. After exploring
- 40:06the petrified trees return the way you came.
- 40:10Let me give you a little more detail than that
- 40:11because finding your way is part of the adventure
- 40:14on this hike. You're going to start by crossing
- 40:16an open sagebrush meadow and there's a good chance
- 40:19you're going to see bison along the way. Give
- 40:21them plenty of room. This first section is relatively
- 40:24easy, although you gradually gain elevation as
- 40:27you cross the meadow. After roughly half a mile,
- 40:30you begin leaving the open prairie and approaching
- 40:32the trees that are straight ahead of you from
- 40:34the parking area. At this point, just keep following
- 40:38the trail up the ridge up the hillside. The route
- 40:41up the ridge is fairly well -worn, so when you're
- 40:44unsure to go, just keep following the most obvious
- 40:46trail upwards. This is the one place where you
- 40:49really don't want to improvise. There are some
- 40:51branches of trails that go left and right and
- 40:54all over. Stay on them. You'll know once you're
- 40:58up there, you're really going to know which is
- 41:00the obvious path, but some of these animal paths
- 41:04do look pretty good, but just know that if you're
- 41:06not climbing, it's probably not the right way
- 41:08to go. At just under a mile, you should be on
- 41:11or approaching the ridge, and the route becomes
- 41:13easier to identify. This is where the hike starts
- 41:16getting much more interesting. You're going to
- 41:18start seeing pieces of petrified wood and smaller
- 41:20stumps along the trail, and as you climb higher,
- 41:22the size and number of the petrified trees that
- 41:25you're going to see increase. You're going to
- 41:28be at this area called the fossil forest, and
- 41:30what you're envisioning right now is not correct.
- 41:33I hate to break it to you. You think fossil forest
- 41:35and you're like, it's a whole forest of petrified
- 41:37trees. When you start going up the ridge, you're
- 41:40going to get near the top of the ridge and then,
- 41:43you know those boot pads I said to ignore earlier?
- 41:45There's going to be one that swings to the right
- 41:47a bit and you're going to see a stump there that
- 41:49looks like a big rock. That's where you want
- 41:51to go. So just swing down there, then you're
- 41:53going to see some really cool things. You're
- 41:55not going to see a whole forest. You're going
- 41:57to see pieces of trees and a good stump with
- 42:00some cool crystals and things like that in it.
- 42:03The tree that you're going to see probably closest
- 42:05up. It's hard to imagine, but supposedly that
- 42:08tree was about 200 feet tall. I've sat and looked
- 42:11at it. I've read this numerous times and my brain
- 42:13can't fathom this, but like it's really cool.
- 42:16If you look at it, there are some cool crystals
- 42:18that are formed inside of it. It's a really awesome
- 42:21piece of petrified wood that is the tree. If
- 42:25you look around, you may see some other ones
- 42:27down in the trees. I don't recommend going down
- 42:30there. I think if you find this big one, then
- 42:33this is kind of the one that you want to see.
- 42:35It's the best experience, the best picture. If
- 42:38you want to do more, fine. But if you want to
- 42:40do something else and make more of a day about
- 42:42it, then continue up the ridge and you're going
- 42:45to hit the top of the ridge. And when you get
- 42:47to the top of the ridge, you're going to look
- 42:48down to the south and you're going to see a trail
- 42:51marker. Go to the trail marker. There's a bison
- 42:54skull there. There's antlers, really cool things.
- 42:57If you do this, know that this is a relatively
- 43:00short hike. It's around four or five miles round
- 43:02trip with about 2 ,000 feet of gain, but if you're
- 43:05not used to the steepness of climb or the footing
- 43:07isn't great, it will be a little harder. So try
- 43:11your best on this. If it's muddy, don't do this
- 43:14one. Reach out to me. I can recommend another
- 43:15trail or you can pick up my hiking guidebook
- 43:17where I have 50 plus of my favorite hikes in
- 43:21the region both in and out of the park to give
- 43:24you the perfect day. But if the weather's good,
- 43:26I think you're really going to like this one,
- 43:28especially when you get through the meadow and
- 43:30then you can start climbing up on the ridge,
- 43:32hang out at the top of the ridge for a while.
- 43:34It's part of the specimen ridge trail that runs
- 43:37from where that new bridge crosses the Yellowstone
- 43:40River all the way to Lamar River and the Lamar
- 43:43River Trail. It's a long day. Not recommending
- 43:45doing that today, but you can see part of it
- 43:48and you can see what the potential of that is.
- 43:51So enjoy that one. I hope you get to hike it.
- 43:54I hope the weather's not too bad and this forecast
- 43:56changes. But if it is, enjoy a rainy day, walk
- 43:59some cool places, go to a lake and watch it rain
- 44:01on the lake and just enjoy nature for the unpredictability
- 44:06that you'll have, but it's always going to be
- 44:09beautiful. Oh, and it should go without saying,
- 44:11but I am going to say it. If you go and hike
- 44:13up the petrified tree where you find the bison
- 44:15skull and you find the antlers and stuff, leave
- 44:17everything there. Do not take anything. I know
- 44:20I said it earlier. I'm going to reiterate this
- 44:22just because I want to be responsible for this
- 44:24podcast and let remind everybody. Leave everything
- 44:27where it is. Keep everything as pristine and
- 44:30natural as possible. If you see trash, pick it
- 44:32up and enjoy your day. Alright, that's it. That
- 44:35is it for this week. In next week's episode,
- 44:38I'll return with all the information you need
- 44:39to have a good week in the park. That includes
- 44:41the wildlife update, the weather forecast, and
- 44:44a trail that I think you should hike. Like I
- 44:46said earlier, next week is going to be a lot
- 44:49about elk, a lot of cool things that I found
- 44:51about the elk, and I'm just going to make sure
- 44:54that you are stoked for the elk rut as I am.
- 44:57Till next week, pick up a guidebook of mine.
- 44:59Recommend this podcast to somebody who's visiting
- 45:02the park book a tour with me for next year and
- 45:05until then happy trails Abrupt ending this week
