About this map

No-Mans Island sits within a complex system of elevated plateaus and deep drainage channels in San Juan County. This landscape is defined by its distinct mesas, including Black Mesa, White Mesa, and Little Black Mesa, which rise above the surrounding terrain. These landforms are separated by carved features such as Black Rock Canyon and the winding course of Cottonwood Wash.

A sparse network of rural routes, including Black Mesa Rd and Ruin Springs Rd, provides access across the arid heights and down toward Decker Cove. The topography reveals a land shaped by erosion, where named points like Ruin Spring Point and broad expanses like Bluff Bench overlook the intricate junctions of the Right Hand Fork Cottonwood Wash. The map reflects a modern period of land management where traditional names for high-desert features persist alongside contemporary county road designations.
