2018 Map of Cadiz Summit

About this map

Cadiz Summit serves as a critical geographic transition point between the Marble Mountains and the Ship Mountains, marking a pass through this arid landscape. The map illustrates the convergence of several major landforms, where the high desert terrain of the Mojave Desert drops into the broad alluvial expanses of Fenner Valley and Cadiz Valley. Settlement is sparse, anchored by the tiny outpost of Cadiz in the southwest, while the desert floor is carved by ephemeral drainage systems like Watson Wash and Vulcan Wash. The prominence of Cadiz Rd as the primary transit corridor highlights the historical importance of this route for crossing the desert long before modern interstates dominated the region. This 2018 survey provides a precise view of the topography and township boundaries, including t6n r14e and t5n-r15e, which define the administrative grid of this San Bernardino County wilderness.
