Mount Anderson

Mount Anderson is a summit in the Olympic Mountains within Olympic National Park, rising to 2,231 meters (7,321 feet) above sea level. The peak sits at the convergence of three major watersheds and is surrounded by active glacier systems.

The mountain received its name in 1897 when Lieutenant Joseph O'Neil mapped the region and honored his commanding officer Thomas M. Anderson. The peak saw its first recorded ascent nearly 25 years later in 1920.

The mountain stands as a representation of Pacific Northwest mountaineering tradition, drawing climbers to its slopes throughout the climbing season.

The best climbing season runs from May through August when snow conditions are most stable and passable. Routes demand experience with snow and ice climbing, along with solid fitness and mountaineering skills.

Three active glaciers cling to different aspects of the peak: Anderson Glacier on the south face, Eel Glacier to the northwest, and Hanging Glacier along the eastern ridge. These ice fields create a striking contrast with the surrounding rock and are visible from lower elevations.
