2014 Map of No-Mans Island

About this map

No-Mans Island and the surrounding high desert terrain define this corner of San Juan County, where high plateaus and deep drainages dictate the local movement. The landscape is characterized by a series of prominent mesas, including White Mesa, Black Mesa, and Little Black Mesa, which rise above the intricate network of canyons and washes. Water drainage is dominated by the Cottonwood Wash and its tributary, the Right Hand Fork Cottonwood Wash, while named points like Ruin Spring Point suggest the deep human history tied to these rare water sources. A sparse network of unpaved tracks, such as Army Rd and Black Mesa Rd, provide the only access through the broken topography of Decker Cove and Black Rock Canyon. Near the southeastern corner, the land levels out slightly onto the Bluff Bench and Big Bench before dropping toward the regional corridor of Us-191.
