About this map

Malheur National Wildlife Refuge encompasses the central portion of this High Desert landscape, where the seasonal waters of Harney Lake and Mud Lake meet a terrain shaped by volcanic and geothermal activity. The hydrology of the basin is marked by several thermal features and seeps, most notably Pronghorn Hot Springs near the shore of the main lake, along with Lynch Spring and Barnhardi Spring. This area is characterized by vast alkali flats and seasonal wetlands, with Weed Lake Flat extending across the southern reaches.

Local infrastructure is limited to primitive routes like S Harney Rd and Catlow Rd, reflecting the remote character of Harney County. Notable topographic features such as Sand Gap provide passage through the rising terrain east of the lakeshore, while Jackass Creek drains toward the basin floor. The map documents the precise boundaries of the wildlife refuge as they interact with the section lines and desert tracks of the Oregon interior.
