Camp Muir via Disappointment Cleaver Route and Pebble Creek Trail(edit)

BASIC GLACIER CLIMB, JUN-AUG From Camp Muir follow obvious traverse of the upper Cowlitz and scramble the Cathedral Rocks Ridge to gain access to the Ingraham Glacier (10,500 ft). Traverse the glacier (Ingraham Flats) to the lower southern base of Disappointment Cleaver. This traverse should be done as quickly as possible due to overhanging seracs. The route onto the Cleaver is approximately 300 ft above the Cleaver's nose. Continue to the top of the Cleaver (12,300 ft), and climb as directly to the east crater rim as crevasses will allow. To gain the true summit, scramble down into the crater and cross directly to the west crater rim. The summit register is just below and northeast of the true summit (14,411 ft) by a large boulder.
