2018 Map of Sierra de la Lechuguilla

About this map

Sierra de la Lechuguilla dominates the northern portion of this map, where the international boundary between the United States and Mexico cuts across the arid landscape. The survey captures a section of the Lechuguilla Desert where complex drainage patterns from La Jolla Wash fan out southward into Mexican territory. This map emphasizes the physical geography of the borderlands, showing how the landform of the sierra dictates the local topography before leveling out into the alluvial plains. Without any modern infrastructure or settlements shown, the document highlights the extreme isolation and preservation of these Sonoran Desert landforms in the early twenty-first century.
