2017 Map of Thompson Mesa

About this map

Blanco Canyon snakes through the northwestern corner of this high-desert landscape on the border of San Juan and Rio Arriba counties. The terrain is defined by dramatic elevation changes, characterized by the broad, flat summit of Thompson Mesa and the prominent overlook at Dufers Point. This area of the Eastern Navajo Agency is primarily accessed by a network of rural routes, including Co Rd 7425 and Co Rd 7575, which navigate the drainages and plateaus. Smaller geological features like Selph Canyon and Blanco Mesa provide significant landmarks for local navigation and land use in this arid region. The map captures the intersection of natural topography and the rectilinear Public Land Survey System, showing the Township and Range lines that organize this corner of New Mexico.
