Ascent Trip Report

Picked up the peak on the way to Twin Peaks. This was part of our 2-day 1-night outing to summit Twin Peaks and Virginia Peak. On the previous day 2020-10-17 we hiked in from Green Creek TH, over the Virginia Pass and arrived at the NW tributary of Return Creek. The camp site was at direct east of Return Lake, at about 9,920 ft elevation. In the morning of 2020-10-18 we started by heading north and crossing the tributary to get to Return Creek. We followed the creek north for a while, and then followed its NE fork to enter the canyon directly west of and below the Yosemite National Park boundary (which is also the Tuolumne County and Mon Country boundary). We did not take the ridge because the ridge was full of boulders and large talus. There was a fainted trail in the canyon to follow. Before the canyon reached the glacier on the topomap, we turned westward and climbed up the ridge. In mid October indeed there was still a big snow field in the glacier. We would circumvent the south edge of the snow field, continued westward and climbed up the slope until we reached the high point of the ridge, which was Twin Peaks-East Peak. The best view was actually further west, on the cliff edge of Horse Creek Glacier. This glacier was massive and it was a great sight to see Twin Peaks, Horse Creek Peak, Matterhorn and the peaks in the north including Robin and Victoria on the Sawtooth Ridge and Eagle Peak on Buckeye Ridge.
