Mount Conness, North Ridge. The north ridge of Mount Conness (12,590 feet) is a mile long cleaver dropping vertically on the east to the Conness Glacier and falling away at 70° for thousands of feet on the west. Barry Hagen and I apparently completed a new route in July when we found no record in either the summit register or the climbing guides. The climbing varies from walking on a level crest to exposed small-hold face climbing on the summit ridge. The granite is among the firmest in the Sierra, making the ascent both safe and pleasurable. NCCS II, F6.
