About this map

Bumping Lake serves as the central focal point of this late-century landscape, positioned at a spillway elevation of 3,426 feet within the Snoqualmie National Forest. The map documents a rugged high-country environment defined by the protected reaches of the William O Douglas Wilderness, where the terrain rises sharply toward prominent summits like Mt Aix and Bismarck Peak.

A network of 4WD tracks provides the only motorized access into the interior, notably leading toward the site of Copper City along Deep Creek. This settlement, alongside family-named landmarks like Nelson Ridge and American Ridge, reflects a history of high-elevation exploration and resource extraction. Recreational infrastructure is clustered primarily around the lake's northern shore, featuring the Bumping Dam, several campgrounds, and a Boat Landing, while the southern reaches remain dominated by glacial basins like Carmelita Basin and numerous alpine tributaries including Ratlesnake Creek.
