2011 Map of Black Rock Springs

About this map

Lone Mountain dominates the high desert landscape of Harney County in this 2011 record of southeastern Oregon. The terrain is defined by its scarce water sources, where isolated points like Black Rock Spring and Indian Spring served as vital landmarks for early livestock grazing and regional travel. To the northwest, the seasonal drainage of Long Hollow Creek carves through the arid landscape, illustrating the hydrological patterns of the northern Great Basin. The map captures a largely unsettled area where the road network consists primarily of unimproved trails and four-wheel-drive paths, reflecting the enduring character of this corner of the state's interior. This survey is a precise documentation of topographic elevations and water locations essential for navigating the high plateau before modern developments significantly altered the landscape.
