The Mountaineer's Route is the classic non-technical alpine route on Mount Whitney and is widely documented in climbing guidebooks and route descriptions. It is substantially steeper and more serious than the standard hiking trail, especially in early season when snow and ice can persist in the couloir and on the Final 400. The route is commonly climbed as a long day or with a bivouac at Iceberg Lake or nearby. Objective hazards include loose rock, snow/ice conditions, and rockfall in the gully. The crux is usually the Final 400, which is a steep class 3 to easy class 4 climb depending on conditions. Route-finding can be important, particularly in the dark or when snow obscures the normal line.
