Yellowstone Hikes - Pebble Creek & Mystic Falls

Friday, August 23, 2024
Silver Gate, Montana, United States
With Yellowstone National Park less than two hours away, I usually make it there a couple times each season, either for a group backpacking trip, some hiking on my own, or playing tour guide to visitors.  Having seen almost all the park’s famous features, unless I’m showing them off to someone I now usually try to get into the backcountry.  My friend David is working in the park as a bus driver this season, so I had someone with whom to hike on his two consecutive days off and also a place to stay.
I got to the employee dorm where he’s staying in the Old Faithful area shortly before noon on the first day, so we decided on a relatively short nearby hike after lunch.  The trail to Mystic Falls leaves from the Biscuit Basin boardwalk.  However, there was a significant explosion of a geyser and Biscuit Basin earlier this summer which destroyed some boardwalk and closed the area. Luckily, there is an alternative trail from the park road to Mystic Falls that skirts the basin.  Altogether, this is a short loop hike of about 3. 5 miles that passes the falls and then continues up the ridge to an impressive overlook of Biscuit Basin and all the way to Old Faithful and the Upper Geyser Basin about 700 vertical feet about the Firehole River Valley.  It was what I consider a nice little afternoon stroll with a view. But it was enough to provoke strong thirst, so we followed it up with some beers at the bar of the Old Faithful Inn, the magnificent log structure that is one of the national park system’s grandest guest lodges.  Time flies when you’re drinking, and before we realized it, it was dinner time.
With two cars between us, I suggested we try a long point-to-point hike rather than an in-and-out or loop to a destination.  The Pebble Creek hike in the far northeast part of the park is one I’ve wanted to do for a while, 12.1 miles from just inside the northeast entrance station to the point where Pebble Creek flows into the Lamar River.
The Pebble Creek hike begins fairly high in the upper part of the Lamar Valley.  It rises rapidly over 1,000 vertical feet to cross the ridge that extends north from 10,354- foot high Baronette Peak, the most prominent mountain in this part of the Absaroka Range.   What’s nice about it is that you get the hard work done first and it’s a very long gradual downhill hike the rest of the way, ending up considerably lower than the hike began.
Once over the ridge, the trail descended a bit into broad meadows between the two prominent ridges, the left side one including Baronette Peak.  This part was my kind of hike – relatively flat and easy and open enough for spectacular scenery in all directions.  It didn’t last for too long, though. As we descended, we were in trees most of the rest of the way, and our bright sunshine gave way to overcast skies, some rumbles of thunder, and a mostly light rain.  Pebble Creek gradually became wider and deeper as it collected the water of more tributary streams, each crossing getting harder to do without getting our feet wet. I ended up just giving up and walking through the ankle to calve-deep water rather than trying to rock hop or balance on a log.
Pebble Creek apparently descends through a canyon before it ends near where we parked. While our trail stayed fairly level, we found ourselves hundreds of feet about the valley floor with a long descent over the last mile or so.  We had more or less dried out from the first rain of the day when the next mini-storm came in to lash us with a few minutes of cold driving rain and painful small hail just before we got to the parking lot.  I was lucky to have a change of clothes in the car.
The day turned out to be quite good for wildlife spotting.  On our long drive to the trailhead we passed hundreds of cars stopped along the road, their occupants watching a black bear in a tree. Once on the trail in the upper Pebble Creek meadows we spied a mother moose with her youngster.  Meanwhile, the Lamar Valley was filled with more bison than I have ever seen in one spot in the park.  August is apparently the rut, and they were far more frisky than usual.  What is it with animals doing their mating rituals right along the road?  Do they enjoy putting on a show for humans?  The numerous bison jams along the road back made for slow going, and it was pretty late by the time I got back home.
