About this map

Swaseys Arch and Obscure Arch define this arid landscape within the San Rafael Swell area of Emery County. The terrain is marked by intricate drainage systems such as Saddle Horse Canyon and McCarty Canyon, alongside more permanent features like the Reid Neilson Reservoir. Local landmarks carry distinctive names such as Devils Monument and the rock formation known as Joe and His Dog.

The presence of Ghost Rock Spr and North Fork Coal Wash suggests the vital importance of water sources in this high-desert environment. Geologic features such as the eponymous The Blocks, Locomotive Point, and Chimney Rock create a complex topography of mesas and draws. This 2017 survey details the intersection of seasonal washes like Cane Wash and Mesquite Wash with elevated plateaus including Cactus Flats and the secluded Secret Mesa.
