About this map

Upper Centennial Flat and the surrounding peaks of the Coso Range dominate this high-desert landscape in Inyo County. The survey records a network of arid basins and thermal geography, including the Upper Centennial Spring and Upper Haiwee Spring, which have historically served as critical water sources in the eastern Sierra region. The terrain is defined by dramatic elevation changes, rising from the Mojave Desert floor toward prominent summits like Silver Mtn, Iron Hill, and Pinon Peak.

Deeply incised drainages such as Centennial Canyon, Lacey Canyon, and Thorndyke Canyon carve through the mountains, illustrating the complex erosion patterns of this volcanic field. This 2015 data reflects the modern topography of a region significant for its geothermal activity and indigenous history, including proximity to documented petroglyph sites. The map also delineates broad alluvial plains like McCloud Flat and Upper Cactus Flat, which characterize the high-altitude desert transitions.
