2023 Map of Mann Lake

About this map

Steens Mountain dominates this portion of Harney County, with its eastern slopes dropping toward the basin of Mann Lake. This high-desert landscape is defined by the sharp vertical relief of the Great Basin, where seasonal water sources like Big Springs, Strode Springs, and Barrel Springs are critical points for local geography. The topography reveals the dramatic volcanic and tectonic history of the region, most notably at the geologic depression known as Hole in the Ground.
