1968 Map of Roll

About this map

The Southern Pacific railroad corridor serves as the primary artery through this arid Yuma County landscape, connecting the small settlement of Roll with the agricultural and ranching operations of the valley. This 1968 study, compiled from earlier aerial photography and field checks, reveals a landscape defined by the intersection of military utility and desert wilderness. The southern portion of the Yuma Proving Ground and other military reservations dominate the central terrain, while the heights of the Castle Dome Mountains and the Kofa Game Range rise to the north. Local life is anchored by features like the Mohawk Valley Sch, Terry Ranch, and several critical water sources including Renner Well and Mesquite Jim Well. The presence of a Canal and multiple Salt Wells indicates the ongoing efforts to manage water for livestock and small-scale settlement in the shadow of the Mohawk Mountains.
