About this map

Uranium prospecting and livestock ranching define the high desert landscape of this 1957 survey. The industrial activity is concentrated in the central and southeastern corridors, where the Poison Canyon Mine, Barbara J No 1 Mine, and Zia Mines suggest a period of intensive mineral exploration across the mesa country. These operations are often located near the base of the dramatic Mesa Montanosa and La Jara Mesa, which dominate the relief.

Settlement is sparse, represented by isolated outposts like Rancho del Puerto and Roundy Ranch. A network of unpaved paths, including a Navajo Indian Trail and various jeep tracks, provides the primary transit through the rugged terrain. Along the ephemeral waters of San Mateo Creek, the presence of Ruins points to earlier habitation, while the eastern portion of the map is protected within the Cibola National Forest.
