Whitehorse Mountain (Lushootseed: čubaliali)[4] is a peak near the western edge of the North Cascades in Washington state.

While not of particularly high absolute elevation, even for the North Cascades, it is notable for its large, steep local relief.

The standard route on the peak is via the Northwest Shoulder, which begins with a difficult trail hike, involves a good deal of snow climbing, and culminates with some exposed scrambling, class 3.

[3][6] Whitehorse Mountain appears in the movie War Games starring Matthew Broderick.

In the scene Matthew Broderick's character is seen using a pay phone at a gas station with Whitehorse Mountain in the background.
