1980 Map of Navajo Reservoir

About this map

Navajo Reservoir dominates this high-altitude landscape where the San Juan River and Los Pinos River meet near the New Mexico and Colorado border. The map captures a moment when the regional infrastructure of the 1970s was firmly established, showing the network of state roads like 550 and 64 that connect the growing population centers of Aztec and Bloomfield. East of the reservoir, the vast expanse of the Carson National Forest is deeply etched by a complex system of drainage ways, including La Jara Canyon and Gubernador Canyon. The topography reveals the transition from the river valleys to the elevated plateaus of Manzanares Mesa and Blanco Mesa, illustrating how the arid geography dictated the placement of early settlements like Blanco and Turley along the life-giving watercourses of the San Juan Basin.
