I'm a bit of a Gore Range n0oB. Backpacking takes too long; hiking takes too long; so it took me awhile to realize that going light, running the access trails, and power hiking the steep slopes to access the interesting stuff is totally reasonable. I only really started visiting Gore summits from the Vail side in the fall of last year (Ripsaw) and their mysterious draw has only grown in that time. I've been fortunate to befriend a group of Eagle runners that share the same running to scramble MO so this summer has been open season.

With warm high pressure extending into October, one last push deep and high into the Gore felt obligatory this autumn. Corey wanted to make a hard effort up to Pitkin Lake and West Partner while I'd been wanting to tackle Rockinghorse Ridge for awhile. So we decided to hammer the run up to Pitkin Lake then tap whatever's left in the tank for a push over to P from West Partner via Rockinghorse, concluded with a reverse traverse below Rockinghorse Ridge above the Upper Piney drainage back south to East Booth Pass and run back out to Booth Falls TH. Brandon Chalk gave great beta on this route. I thought the ridge could use a little more insight from the perspective of a rapid strike as opposed to climbing each and every spire in the course of a long day.

After originally planning on an 0530 start, we realized it's October. And Dark. And Cold. We pushed our start time back to 0630, even though... Still dark. Still cold (25F). I have no photos of the approach along Pitkin trail because I was mouth breathing through the entirety of it. Shockingly, a few flurries flew shortly before our arrival at Pitkin Lake before the skies completely cleared. The warm inviting alpenglow on the Partners hung only a couple hundred feet overhead. It taunted us while I warded off frostbite filling my bottles in a stream.

We ascended the grassy slopes south of West Partner mercifully meeting the sun halfway. After gaining the false summit visible from Pitkin Lake, the scrambling commenced. It was mostly a 3rd class blocky ridge run. Most of the exposure to the east was avoidable to the west typical of the range. I decided to have a go at a down sloping knife edge on the ridge proper. It abruptly ended in a cleft with a tricky down climb required to get off. Corey easily skirted it on a ledge west.

From West Partner, the descent onto Rockinghorse ridge started as an innocuous walk off. Before long, the terrain steepened drawing us back toward the ridge proper. Most difficulties could still be bypassed to the west.

We bypassed all the towers besides Rockinghorse. From below the ridge proper, it was a direct climb from the west up to Rockinghorse. Corey gained it with some class 3-4 ledges on the west. I climbed it from the south with an awkward arm jam into an offwidth and some smearing. Felt like low 5th class without much exposure - 15 foot climb from a ledge.

We had assumed we were past the difficulties of the ridge after summiting Rockinghorse until we walked upon the edge of a 40 foot cliff guarding a gully. I assumed I could skirt it with a short scramble down off ridge, but the cliff extended around to the west and south forming a peninsula around us. Barring backtracking and down climbing a couple hundred feet, it seemingly severed further access north.  Corey discovered a single crack in the face of the cliff that we were able to down climb at 4th-5th class. The exposure was a bit unnerving. This was near the low point of the ridge.

The start of the climb from the the saddle onto the P ridge had another shorter, though equally tricky, down climb into a notch before a 2nd class ascent to P's summit. The summit of P offered impressive views of Q, L, Ripsaw, the Partners and the Spider. It's the deepest I've felt in the Gore thus far- only about 3.5 hours from the trailhead.

We backtracked along P's ridge and started descending west from the ridge before the the last notch we had previously down climbed. From there it was traversing on grass and talus blocks above Upper Pitkin Lake over to East Booth Pass. East Booth Pass had a beautiful view into the Booth drainage and the upper tarn. From here, it was an easy descent on grass to the tarn followed by a steep grassy gully down to the lower lake and main trail where we were able to quickly descend to the golden valley below in under 6 hours roundtrip car to car.
