"Second time at this summit made for a great Labor Day! Started at 5 and the trail was quite busy. Summitted with Ryan Byers and some of his Pocatello friends (Spencer, Adria?, Alex). Very clear day, even calm air at the summit. Chicken out is much less scary the second time 'round. No snow bridge made the route feel much safer. Good to be back up there!" - Borah Peak, robkleffner, Sep 3, 2018
"This is my new favorite, but holy toledo is it a long one. It's a lot like Hyndman Peak but more varied and certainly more technical. Whereas with Hyndman it's hard to get yourself in a pickle, this one presents challenges at several points, which makes it a lot more fun but also less accessible. Beautiful approach on the ridge, even among all the smoke, and it turned out to be less smoky than previously in the week. A pair of girls working in Stanley for the summer (Kelsey and Ellie, if I remember correctly?) passed me, and I them, at various points throughout the climb, and they were nice en" - Thompson Peak, robkleffner, Aug 25, 2018
"This extremely loose scramble was a bit more than we'd bargained for, but ultimately successful. Basically, from the south side, follow the boot "pack" through the lower slope's scree, then head up the gully that heads most directly towards the true summit, staying to the west side or wherever you see solid-ish rock with the least build-up of erosion from above. When you reach the notch on the summit ridge, curl around the north side of the summit block. Tom had to stop for a brief puking break. I'm glad that we succeeded, but really, I wouldn't recommend this choss pile to anyone, despite it'" - Castle Peak, TynanRammGranberg, Sep 7, 2017
"3rd and final day in Idaho. After Thompson and Borah, legs felt a bit leaden at the start of this classic Idaho 12er, the highest in the Pioneer Range. After a flat hike for 2.5 miles through wide meadows and aspen groves, the warmup's over. From then on out it's Game of Vert. Climbing in an alternating steep-flat rhythm, the trail finally reaches Sundance Lake at the foot of the towering Hyndman Peak. From here it's a puzzle to get to the saddle between Hyndman and Old Hyndman while avoiding as much talus as you can (if you veer right in the middle of the first talus field you'll find a g" - Hyndman Peak, scott, Aug 28, 2016
"Helloooooo Idaho! The entire state was on a quest to climb to the top of Idaho today, all ages, all body types, all outfits. The TH parking was completely full @8am when we started up the Borah Peak Trail aka nature's stairmaster. This trail doesn't mess around and seems to crave vert. We motored up in cool temps gaining thousands of feet with only 1 stop for Josh to heed nature's call. So many people out here. We passed all sizes of groups as we made our way up the open slopes and to the infamous scramble section of Chicken Out Ridge. It was a light-hearted but exposed scrambling traverse," - Borah Peak, scott, Aug 27, 2016
