2023 Map of South Mountain

USGS Topo · Published 2023

About this map

The Malheur River cuts across the southern portion of this high-desert landscape, serving as a primary hydrological artery for a network of seasonal streams and springs. High-elevation water management is evident throughout the terrain, with features such as South Mountain Reservoir, Alfred Reservoir, and Hog Cr Reservoir Number Two strategically placed to collect runoff from the slopes of South Mtn and Hog Creek Ridge. These catchments, alongside named watering points like Boney Spring Number 1 and Rimrock Spring, highlight the essential infrastructure required for ranching and land use in this arid region. The topography is defined by deep incisions like Black Canyon and Red Rock Canyon, which drain into the river valley. Sparse transport routes, including Shelley Rd and Antelope Spring Rd, provide the only modern access through the township and range sections that divide this remote corner of Malheur County.
