The high mesas and deeply incised canyons of San Juan County are captured here in a 1952 survey by the U.S. Geological Survey. This preliminary edition, derived from 1951 aerial photography, focuses on the elevation changes across landforms like Dry Mesa and Black Point. The map provides a look at the landscape's natural drainage and catchment points, exemplified by a single Reservoir located just below the northern rim of Short Canyon. The terrain is characterized by dramatic escarpments and plateau surfaces, including the expansive Lean-To Point in the northeast and Lower Horse Flats to the east. Navigational landmarks like Indian Head serve as prominent points of orientation in a region defined by its complex topographic relief and isolated high-desert plateaus.
