2021 Map of Chupan Mountain

About this map

Chupan Mtn and the southern Mesquite Mountains define this Pima County landscape, where topographic contours reveal a high-relief basin-and-range environment. The map details a transition from the elevated peaks of Mamtotk Peak down into the expansive alluvial floor of the La Quituni Valley and Kom Vo Valley. This recent survey by the U.S. Geological Survey captures the modern topography of these landforms, illustrating how the drainage patterns and desert terrain have been shaped over millennia. While the area remains largely undeveloped, the Public Land Survey System grids, including t17s r2w and t18s r1w, provide a framework for locating specific points of interest in this corner of the Sonoran Desert. The intersection of three distinct valleys—the La Quituni, Kom Vo, and Quijotoa Valley—highlights the complex hydrology and geography found within this region.
