2018 Map of Red Hill

About this map

The Trigo Mountains and Chocolate Mountains dominate this high-desert landscape in La Paz County, where intricate drainage patterns define the arid terrain. The map reveals a complex network of seasonal watercourses, including the prominent McAllister Wash and Yuma Wash, which carve through the volcanic and sedimentary formations. Prominent peaks such as Trip Mtn and the namesake Red Hill provide clear navigational landmarks within the vast, uninhabited stretches of the Sonoran Desert. This 2018 survey serves as a precise record of the landforms and dry-wash geography before further natural erosion or modern land-use changes alter these remote mountain ranges. It is particularly useful for understanding the physical barriers and natural corridors that have historically dictated travel and survival in this corner of Arizona.
