2014 Map of Middle Mountains South

About this map

Middle Mountains dominate the northwestern landscape of this Yuma County survey, characterized by a series of prominent peaks and the notable Natural Arch formation. The terrain transitions from these high points into the expansive Castle Dome Plain to the southeast, a broad alluvial expanse defined by the drainage of Castle Dome Wash. This ephemeral watercourse cuts a diagonal path across the quadrangle, paralleling the modern corridor of Us-95. The road network is sparse, with Ocotillo Rd providing one of the few named access points into the desert interior. The map illustrates the structured division of public lands, showing the intersection of several townships including t5s r20w and t6s r20w, reflecting the systematic surveying of the Arizona desert during the early 21st century.
