2012 Map of Upper Centennial Flat

About this map

China Lake Naval Weapons Ctr borders the southern portion of this high-altitude desert landscape, marking the intersection of military restricted space and the open Inyo County backcountry. The topography is defined by significant elevation changes between the peaks and the broad, dry basins, such as Joshua Flat in the north and McCloud Flat to the southwest. Water remains the critical resource of this arid region, as evidenced by Upper Centennial Spring and Upper Haiwee Spring. These vital points of moisture likely served as historical landmarks for travelers moving between the drainage of Centennial Canyon and the surrounding heights of Silver Mountain and Pinon Peak. The map provides a clear record of the primitive road network that connects these remote features across the expanse of Upper Centennial Flat.
