Climbing the Northeast Buttress
From Independence on US 395, drive Onion Valley Road about 13 miles to the Onion Valley trailhead. Cross Kearsarge Pass, pass Bullfrog Lake to the John Muir Trail, and descend to Vidette Meadow. Cross Bubbs Creek and follow a faint use trail up the west side of Vidette Creek past the Vidette Lakes. Climb the Class 3 Northeast Buttress of the lower northwest peak, traverse sandy ledges down to the notch, and scramble to the small southeast summit. The scree at the base of the buttress needs care. Plan two or three days. An Inyo National Forest wilderness permit is required, and Kearsarge Pass quotas fill early.
