2021 Map of North of Roll

About this map

The arid desert floor of Yuma County rises sharply into the Castle Dome Mountains in this modern topographic study. The landscape is defined by the stark transition from flat desert basins to the craggy elevations of the Black Hills, illustrating the dramatic basin-and-range topography typical of the region. The primary human imprint on this wilderness area is Wellton Kofa Rd, a long north-south corridor that provides the only significant access through these remote sections of public land. This 2021 edition serves as a precise baseline for understanding current land use and accessibility in a part of Arizona where natural geography still dictates movement and activity.
