About this map

The Desert Experimental Range dominates this 1970s landscape in Millard County, representing a significant scientific effort to study arid land ecology. This high-desert environment is defined by the sharp transition between the Antelope Valley to the west and the Tunnel Spring Mountains and Pine Valley to the east. Several designated Experimental Plot locations and larger Experimental Plots are scattered across the terrain, indicating the systematic research being conducted on the local flora and soil.

Water management in this dry region is evidenced by features like the East Antelope Reservoir and Tunnel Spring, which provide critical resources in an area otherwise carved by the ephemeral Antelope Valley Wash. The rugged topography of the Halfway Hills and Warm Cove Ridge separates the valleys, while the presence of a Borrow Pit and the lonely stretch of Cowboy Road highlight the sparse human intervention and infrastructure required to maintain this remote research station.
