South Ridge, Class 4

Follow the Boulder Lake Trail [(FST-057 (C)(1)(a) on Page 259] to Boulder Lake. Circumnavigate the lake on its west shore and ascend the eyebrow cliffs from their West Side. From here, ascend to the east on steep talus towards Point 11024, eventually bearing north past this point on the west. Cross ribs to reach ledges and short gullies that lead to the knife-edged ridge below the summit. George Reinier and Pat McGrane reached the summit on August 21, 2008 with no signs of previous ascent.
