About this map

Bumping Lake and its surrounding high-elevation landscape are documented here as they appeared in the late 1980s. The reservoir, regulated by Bumping Dam with a spillway elevation of 3,426 feet, serves as a central hub for activity within the Snoqualmie National Forest. The map illustrates a network of recreational sites, including the Bumping Lake Campground, a Picnic Area, and various boat facilities. A flume and the winding Bumping River provide insight into the local water management and drainage patterns that define this valley.

Away from the water, the terrain is characterized by steep ridges and peaks such as Mt Aix and Bismarck Peak. The presence of Copper City near Deep Creek and Miners Ridge suggests a history of mineral exploration in the shadow of the William O Douglas Wilderness. Remote alpine water bodies like Granite Lake and Root Lake are accessible via established trails and 4WD routes, highlighting the balance between protected wilderness and forest service access.
