Ascent Trip Report

10/17: Had lunch at Bridgeport and self register for wilderness permit at Bridgeport Ranger Station. From Ranger Station, drove on Hwy 395 South and turned into Green Creek Road. Enjoyed full display of Fall Foliage on the way before reaching the Green Creek Trailhead Parking. The parking lot was full so we drove a little further towards the Green Creek Campground and parked on the side of the road right at the entrance of group camp. The campground was closed but we used the bear boxes there to store our food items and anything with ascent. We hiked the Green Creek Trail with a backpack for one night, passing the north and west shores of Green Lake before reaching Virginia. From Virginia Trail we followed the northbound use trail for a while before heading down straight to Return Creek. We crossed the creek and decided to set up out camp by its fork. There was water on Return Creek and its fork so there were plenty of places to choose for the tent side but we chose one that was close to the hill and trees so that we have some shield from the wind. However it was a very clear night without almost any wind. The overnight temperature dropped below freezing though, perhaps in the 28-30 degrees neighborhood.

10/18: From the camp we first hiked up to Twin Peaks-East Peak (see that report on this part of the hike). From East Peak it was a straightforward traversal to Twin Peaks. I aimed for the summit on the north while Will and Ken aimed for the summit on folks' GPS tracks. The north summit had a greater view, while the south summit was where the summit register was placed. Will and Ken joined me in the north summit shortly, then together we went back to the south summit where I dutifully signed my entry. After a short break on the south summit, we took on the fairly exciting class-3 traversal to Virginia Peak (see report on Virginia Peak for this section). After Virginia Peak we hiked down to our campsite, retried out tents and organized out backpacks. Then we hiked out to the trail head.

The GPS track has only the ascent portion of the hike. The descent portion is attached to the Virginia Peak report.

South summit of Twin Peaks, where the summit register was located, taken from the north summit of Twin Peaks. Mount Conness is right behind. Left of Conness one can find Mount Ritter and Banner Peak. Right of Conness one can see the highest ridge of Yosemite NP, with Mount Lyell and Mount Maclure. Later we would traverse the ridge from the summit to Virginia Peak, on the lower right of the photo (2020-10-18). Photo by Yao-Min Chen.
