1988 Map of Yamsay Mountain

USGS Topo · Published 1988

About this map

Yamsay Mountain dominates this portion of the high Cascades, where the borders of Winema National Forest and Fremont National Forest meet. The landscape is defined by the volcanic topography of Buck Ridge and Booth Ridge, intersected by a complex network of seasonal drainages including Bear Creek and Deep Creek. This 1980s-era survey preserves the alignment of the Old Indian Treaty Boundary, providing a specific historical marker of land tenure in Lake and Klamath counties. The map details a wild, hydrologically active area characterized by numerous water sources such as Blue Buck Spring and Antler Springs, which feed into meadows like Calahan Meadow. Evidence of resource extraction appears in the form of a Cinder Pit, while the rugged drainage systems of West Fork Silver Creek and Guyer Creek underscore the area's role as a vital watershed.
