About this map

The high alpine crests of the Entiat Mountains and Chelan Mountains dominate this 2023 survey of central Washington. The landscape is defined by the convergence of protected wilderness areas, including the Lake Chelan National Recreation Area, Stephen Mather Wilderness, and Glacier Peak Wilderness. This intersection of federal lands preserves a terrain of steep peaks and high basins, such as the Fourth of July Basin and the expansive Entiat Meadows at the headwaters of the Entiat River.

Tracing the hydrological patterns reveals numerous drainages like Railroad Creek and Sevenmile Creek that cut through the complex topography toward Lake Chelan. Hikers and researchers can follow established paths including the Lower Railroad Cr Wilderness Trl and Monkey Bear Falls Trl which provide access to remote water bodies like Mirror Lake and Dole Lakes. The presence of several "PB" or protracted block labels indicates areas where traditional township and range surveys were deferred due to the challenging terrain.
