1950 Map of Little Black Peak

About this map

The Malpais dominates the southern landscape of this 1950s study, where ancient Lava flows create a stark contrast against the surrounding high desert. This geological feature is anchored by Little Black Peak and sits just west of the rising Sacramento Mountains. The Southern Pacific railroad corridor serves as the primary artery through the region, connecting the small settlement of Ancho and the siding at Cooper to the broader territory. Local topography is defined by significant drainage systems including Largo Canyon and Coyote Canyon, which cut through the terrain toward the Lincoln National Forest. Historical interest is peaked by the presence of Ruins located near Ancho Valley, suggesting earlier habitation or ranching activity in this arid environment near the Socorro and Lincoln County line.
