About this map

Radar Mine, White Cow Mine, and the Ada Bell Mine anchor the eastern plateau of this Montrose County landscape, highlighting a history of mineral extraction in the high desert. The terrain is defined by the significant break at Lisbon Gap, where the higher elevations of Island Mesa and Middle Mesa overlook the Lower Libson Valley. A complex system of drainage and erosion is evident through the deep incisions of Lisbon Canyon, Island Canyon, and Snyder Water Canyon.

Transportation through this arid reach follows established routes like Island Mesa Rd and Patterson Ranch Rd, which connect the scattered mining operations to the broader region. The map captures a high-plateau environment where water is a seasonal force, carving features such as Coyote Wash and Greasewood Canyon through the sandstone layers, creating a distinct geological record of the Colorado-Utah borderlands.
