1980 Map of Southeast Harney Lake

About this map

The Malheur National Wildlife Refuge dominates this desert basin, illustrating the complex hydrology of the high desert during the 1970s. The landscape is defined by the expansive, often dry beds of Harney Lake and Weed Lake Flat, where geothermal activity is evident in named features like Bathtub Spring (Hot) and other Springs (Hot). This survey captures the transition from the shifting Sand Dunes in the north to the low-lying Alkali Flat, a region where water is a scarce and precious resource, marked by scattered water sources such as Lynch Spring and the drainage of Jackass Creek. Small-scale exploration is noted in the hills near the eastern boundary, where Prospects suggest historical interest in the area's geology.
