2021 Map of Clark Lake NE

About this map

The Santa Rosa Mountains dominate this high-desert landscape along the border of Riverside and San Diego Counties. This 2021 survey captures the dramatic topography of the region, where the steep grades of Buck Ridge drop into the deep recesses of Rockhouse Canyon and Martinez Canyon. The map reveals a land defined by its natural barriers and drainage patterns, with the northern reaches of Clark Valley visible at the southern edge of the sheet. To the west, the contours of Butler Canyon underscore the isolation and difficult terrain of this part of the California desert. The lack of modern road infrastructure throughout much of this quadrangle emphasizes the area's role as a vast natural corridor between more developed regions of the Colorado Desert and the surrounding mountain ranges.
