1986 Map of St. Patrick Mtn.

About this map

St Patrick Mtn dominates this high desert landscape, surrounded by a complex network of water management features essential for rangeland survival. The map reveals the critical importance of water in this arid stretch of Lake County, marked by numerous named catchments such as Settlement Waterhole, Coyote Bedground Reservoir, and Sioux Reservoir. To the south, the dramatic geologic drop of the Diablo Rim gives way to the broad expanse of Diablo Flat, while the central portion of the map is defined by the winding depression of Coffee Pot Basin. Smaller topographic details like Rocky Butte and Bunker Hill rise above the canyons, providing landmarks between seasonal water bodies like Coffee Lake and Spur Rowel Lake. The inclusion of Emery Well and several state game reservoirs suggests a landscape managed for both livestock and local wildlife during the mid-1980s.
