2002 Map of Mount Lago

USGS Topo · Published 2006

About this map

Mount Lago stands as a central landmark within this high-elevation landscape of the Okanogan National Forest, where steep ridgelines and alpine basins define the northern Cascades terrain. This 2002 revision by the Forest Service highlights a network of dramatic summits including Ptarmigan Peak, Osceola Peak, and Blackcap Mountain. The hydrology of the Pasayten Wilderness is documented through the headwaters of Eureka Creek and Ptarmigan Creek, which drain a series of high-mountain basins containing Lake Doris, Ferguson Lake, and the Dot Lakes. The presence of the Monument Creek Trail and various named passes like Shellrock Pass and Butte Pass indicates the established routes used by backcountry travelers and forest rangers throughout the late 20th century. The map provides a detailed record of glacial features and drainage patterns, such as the Middle Fork Pasayten R and Lease Creek, within one of the most protected wilderness areas in the state.
