About this map

The Blocks name this high desert landscape in central Utah, where a network of dry washes and deep canyons defines the topography. Photogrammetric data from the 1970s reveals a land sculpted by erosion, featuring uniquely named landmarks such as Devils Monument, The Twin Priests, and Joe and His Dog. The drainage patterns are dominated by Coal Wash and Cactus Wash, while high points like Locomotive Point and Secret Mesa tower over the surrounding flats.

Evidence of human activity is concentrated in cattle ranching infrastructure and geological exploration, represented by the Reid Neilson Reservoir and scattered Drill Hole sites. Movement through the area in the late twentieth century relied on a network of rugged tracks, including the Devils Racetrack and various Jeep Trails. The southeast corner transitions into the Head of Sinbad, marking a critical juncture near the modern path of Interstate 70.
