About this map

The Alpine Lakes Wilderness and Wenatchee National Forest converge in this high-altitude survey of Kittitas County, where the Pacific Crest National Scenic Trail winds through complex glacial terrain. The hydrography of the region is centered on the deep basin of Kachess Lake and the smaller Cooper Lake, fed by an intricate network of waterways including the Cooper River, Waptus River, and Lemah Creek.

Elevations vary significantly across prominent landforms such as Polallie Ridge, Chikamin Ridge, and Red Mountain. For the backcountry researcher, the map details a dense system of historic access routes, including the Escondido Lake Trail, Waptus Pass Trail, and Tired Creek Trail. These trails link remote water bodies like Diamond Lake, Pete Lake, and Little Joe Lake, illustrating the logistical connectivity of this wilderness landscape in the early 21st century.
