Dead Dog is the main couloir on the east face of Torreys. Approach via the Stevens Gulch trail, and drop down into the basin to the base of the couloir when directly opposite it. Trudge up the runout and into the main couloir, where by late May or June hard snow or runnels of ice will be waiting for you. Wear a helmet and get an early start, as the upper couloir sheds rock as the sun warms the walls. The upper half of the couloir averages 45 degrees, maybe a fuzz more, and deposits you 150-200' below the summit.
