About this map

Whitehorse Mountain and its surrounding peaks define this high-elevation region of Snohomish County. The landscape is characterized by prominent geological features such as the So-Bahli-Alhi Glacier and high-altitude basins like Wellman Basin and Sill Basin. This 2011 survey documents a topography where water sources originate at the heights of Mount Bullon and Three Fingers, feeding into complex drainage systems like Boulder River and Squire Creek.

The map details several high passes and saddles, including Lone Tree Pass and Tin Can Gap, which serve as natural transit points through the steep terrain. For those interested in the hydrology of the Cascades, the map traces numerous named alpine lakes such as Bullon Lake, Tucker Lake, and Noble Lake. The network of Forest Service roads, including 4130 and 2030, illustrates the modern access points into these protected mountain wilderness areas.
