1990 Map of Cholla Tank

About this map

The Kofa National Wildlife Refuge dominates this desert landscape, where the sharp rise of the Kofa Mountains and the Little Horn Mountains meets the broad Ranegras Plain. This 1990 provisional survey records a territory defined by aridity and extraction, where vital water sources like Cholla Tank, Craven Well, and Red Rock Dam served as critical landmarks for travelers and prospectors alike. The presence of the Kofa Manganese Road and scattered Prospects near the La Paz Co Yuma Co boundary points to the region's mineral history. Navigation through these desert ranges relied on established routes through natural gaps like Red Rock Pass, connected by a network of unimproved tracks and a primitive Pack Trail. The drainage patterns of Alamo Wash and Red Raven Wash further illustrate the watershed dynamics of this protected Arizona wilderness.
