The Granite Mountains and Palen Mountains converge in this arid Riverside County corridor, defined by the strategic crossing of Palen Pass. This 1983 survey documents a landscape shaped by extreme topography and sparse water sources, such as Packard Well and the ephemeral Sand Draw. The map reveals a history of resource extraction, indicated by several Mines tucked into the mountain slopes, and a primitive transportation network consisting of a winding Jeep Trail. Survey markers like BM 14 GWM 4490 and BM 16 GWM 3294 provide precise elevation data for the complex terrain. The drainage patterns of various Dry Wash features illustrate the geological character of this desert interior, where human presence is largely limited to mining and seasonal passage.
