1969 Map of Mount Lago

USGS Topo · Published 1973

About this map

The high peaks of the Cascade Range define this 1969 survey of the Okanogan National Forest, where steep ridgelines and glacial cirques harbor numerous alpine lakes. Mount Lago and Osceola Peak anchor the central topography, part of a high-elevation network of summits that includes Ptarmigan Peak and Mt Carru. This area, protected within the Pasayten Wilderness, is characterized by its lack of roads, instead relying on a system of Pack Trails that connect remote water bodies like Lake Doris, Ferguson Lake, and Lease Lake. The hydrology is dominated by the headwaters of the Middle Fork Pasayten River and the South Fork Pasayten River, which drain the northern slopes toward the Canadian border. Key navigational landmarks for early backcountry travel are noted at Butte Pass and Shellrock Pass, providing transit points through the high terrain between Eureka Creek and Monument Creek.
