Pahsimeroi Pyramid is located on the main Pahsimeroi Crest just south of Metaxy Peak. It is a visually stunning peak. USGS Grouse Creek Mountain
Access
Same as for Metaxy Peak. This is the second leg of a 2-peak journey that includes Metaxy Peak (10,757 feet) and Pahsimeroi Pyramid. It covers 7.5 miles with 3,650 feet of elevation gain round trip.
Northwest Ridge, Class 2
The Climb
From the 10,180-foot connecting ridge, scramble southeast up the ridge crest on steep-ish scree with occasional help from a goat trail. Stay on the ridge crest for the best footing. There are no rocky ridge outcrops to navigate. The summit is a small ridgeline high point with a modest cairn.
Southeast Gully, Class 3
The Descent
From the summit, descend east briefly on a shoulder to reach the head of the [obvious] southeast gully. Leave the shoulder and carefully descend steep, loose talus to reach the center of the gully. Follow the center of the gully on scree/gravel with the help of a goat trail. You can boot ski much of it. Lower down, the gully has a hidden headwall that requires the downclimb of two separate Class 3 chutes. Once at the base of the gully, there is a flat, grassy patch with pine forest nearby. This point is still over 400 vertical feet above the valley floor.
Descend a combination of cliff bands and pine forest (with some brush) to get down to the short grass (and a dried-up pond shown on the USGS topo map) on the valley floor. From the dried-up pond, hike northward along the base of the mountain cliffs to the right/east to reach the critical valley junction that separates Peak 10340 from Point 10676. Scramble northeast up a forested headwall then bushwhack left/north to reach the rounded shoulder and Point 8662. Follow the semi-open shoulder northeast to intercept the old 2-track road and follow it back to your parked vehicle.
