About this map

Yamsay Mountain dominates this portion of the Oregon high country, where the borders of Klamath and Lake Counties meet. This late-twentieth-century revision by the USDA Forest Service details the complex hydrology of the Fremont National Forest and Winema National Forest. A dense network of water sources, including Blue Buck Spring and the headwaters of Bridge Creek, suggests a landscape managed for both timber and seasonal grazing.

The presence of the Cinder Pit near the northern boundary points to the volcanic origins of the terrain, specifically along the elevated spines of Buck Ridge and Booth Ridge. Low-lying areas like Calahan Meadow provide a contrast to the ridges, served by numerous small tributaries such as Guyer Creek and West Fork Silver Creek. The map documents the Forest Service's road system as it stood at the end of the century, providing clear coordinates for the remote springs and creeks that define this montane environment.
