San Juan Basin Gas Field infrastructure dots the high desert landscape of San Juan County in this 2013 survey. The terrain is defined by a complex network of dry washes and deep incisions, most notably Cañon Largo and the expansive Blanco Canyon. The drainage pattern is anchored by the Blanco Wash, which cuts through the southwestern corner of the sheet. Modern access is facilitated by graded paths such as Co Road 7007 and Carrizo Rd, reflecting the region's continued importance for resource extraction.
