Climbing the North Slopes via Lake Canyon
From Lee Vining, drive US 395 north about 7 miles and turn west on Lundy Lake Road to its end beyond Lundy Lake. Take the Lake Canyon trail up past old mine ruins to Oneida Lake, where the trail fades. From there, travel cross-country up the north side of the mountain over long talus and boulder fields to the summit. The SPS rates it Class 1, though some boulder hopping touches Class 2. This north-facing side holds snow into early summer, so carry an ice axe before July. Loose rock and the missing trail make for a long day, so start early to stay ahead of afternoon storms.
