About this map

Black Mesa and White Mesa dominate this high-desert landscape in San Juan County, illustrating the dramatic geological relief typical of the Colorado Plateau. This 2010 topographic record highlights the isolated No-Mans Island and the expansive Bluff Bench, areas defined by their limited accessibility and significant vertical drops. The map documents a sparse human imprint, primarily represented by cattle-ranching infrastructure such as the Decker Ranch and a network of unpaved access routes like South Cottonwood Rd and Butler Wash Rd.

Drainage patterns are clearly articulated through the complex systems of Cottonwood Wash and Black Rock Canyon, which carve through the sandstone formations. The geography here is a study in upland plateaus and deep-cut washes, including the Little Black Mesa and Big Bench. Points of interest for navigation and geography include the White Mesa Overlook and Ruin Spring Point, reflecting the intersection of natural landmarks and seasonal water sources in a demanding environment.
