About this map

John Mills Lake and its associated John Mills Lake Dam form the centerpiece of this northern Rio Arriba County landscape. The terrain is characterized by a network of drainage systems, including the prominent Burns Canyon and Dulce Canyon, which wind through the high desert floor toward the northern border. Near the northeastern corner, Dulce Lake sits adjacent to Cordova Canyon, providing a critical water source in an otherwise arid environment.

Evidence of historical land use and named local geography is visible in landmarks such as Piedra Agujero and Burns Hill. These features, along with Puerto Spring, indicate a reliance on specific topographic markers and reliable water points for navigation and ranching in this part of New Mexico. The map illustrates how local infrastructure follows the natural contours of the canyons, tracing the relationship between the hydrology of the region and human movement across the territory.
