2011 Map of Twin Buttes

About this map

Jackass Creek meanders through this arid landscape, defining the hydrologic network of this portion of Harney County. The area is characterized by an extensive system of water management features, including Long Canyon Reservoir, Second Lake Reservoir, and Larrys Reservoir, which support life and agriculture in the high desert. Notable topographic landmarks such as the Twin Buttes and the open expanse of Weed Lake Flat provide orientation in this sparsely populated region. The map also documents numerous named waterholes, such as Mammoth Waterhole and Tooney Waterhole, which are critical points of interest for local history and ranching operations. Significant local thoroughfares like Catlow Rd and Foster Flat-Harney Lake Rd connect these remote water sources and landforms.
