2011 Map of Yamsay Mountain

About this map

Yamsay Mountain dominates this portion of the Oregon landscape, serving as a primary hydrologic hub for several drainages including Knight Creek, Jackson Creek, and the headwaters of Buck Creek. The terrain is defined by a series of prominent elevations such as Jackson Ridge, Buck Ridge, and Booth Ridge, which channel seasonal snowmelt into complex creek systems. Evidence of high-altitude forest management and recreation is seen at Blue Buck Camp and the nearby Blue Buck Spring. The presence of Antler Springs and Calahan Meadow suggests localized areas of moisture that support distinct ecology compared to the surrounding ridgelines. Navigating this area relies on an intricate network of forest service roads, including routes like 7645 and 024, which provide access to these remote volcanic slopes and riparian corridors like West Fork Silver Creek.
