Burroughs Mountain is a high ridge on Mount Rainier’s northeast slope above Glacier Basin, known for hiking from the Sunrise area and for expansive above-tree-line views of Rainier’s northeastern glaciers and nearby peaks. Named for naturalist John Burroughs, the place received its present official name in 1932. Geologically, it is an ancient andesitic lava flow at Mount Rainier’s northeast foot, forming three summit plateaus of increasing height. Its alpine tundra supports hardy plant life and animals such as marmots, pikas, mountain goats, and chipmunks. Though beautiful and accessible in season, the area is fragile, with snow, ice, and off-trail travel posing hazards to both visitors and the tundra.
