1967 Map of Cerro Alto

About this map

The Ramah Indian Reservation Boundary defines the structural layout of this high-desert landscape, where land use and topography are closely linked. Crossing the center of the sheet, the Continental Divide separates the drainage basins of the American West, winding past volcanic landmarks like Cerro Alto and Cerro Flora. The presence of ephemeral water sources such as Laguna Flora and Laguna Colorada indicates the critical importance of seasonal moisture in this arid environment. Further topographic variation is found in the expansive Flat Peñasco and the distinct lowlands of The Vega. The map's detailed fencing lines and section markers suggest a terrain utilized for grazing and traditional land management within and adjacent to the reservation during the late 1960s.
