About this map

San Rafael Desert topography dominates this 2020 survey, revealing a landscape defined by dramatic geological features and isolated water sources. The prominent elevation of Jacks Knob stands as a central landmark, while the intricate contours of Sweetwater Reef and Red Reef illustrate the complex erosion patterns typical of Emery County. Reliable water is scarce in this arid environment, marked primarily by scattered points such as Dugout Spring, Lower Dugout Spring, and Twin Springs.

Ephemeral drainages like Moonshine Wash and Dugout Wash dissect the terrain, leading toward larger depressions such as Middle Canyon. Human presence is minimal, represented by primitive roads like Co RD 1011 and industrial infrastructure noted at Moonshine/Saucer Basin Wells. This map provides a detailed look at the fundamental landforms and vital springs that have dictated navigation and survival in this portion of the Utah desert for generations.
