2014 Map of Jacks Knob

About this map

San Rafael Desert topography dominates this Emery County landscape, where water sources dictate the geography of a dry environment. The presence of numerous watering points, including Lower Dugout Spring, Upper Dugout Spring, and Twin Springs, suggests the historical importance of these sites for ranching and overland travel. The terrain is defined by dramatic geological features such as the Sweetwater Reef and the prominent high point of Jacks Knob. Drainage patterns are carved through the desert floor by Moonshine Wash, North Spring Wash, and Dugout Cr. While modern county roads like CO Road 1011 cross the expanse, the names attached to the land—from Red Reef to Middle Canyon—reflect the long-standing vernacular of local navigation and land use.
