1964 Map of South of Yuma

About this map

The Yuma Desert dominates this arid landscape along the international border, as surveyed in the early 1960s. The map illustrates the sparsely populated expanse where the United States-Mexico boundary line cuts southeast across the desert floor toward the Arizona-Sonora line. Human activity is largely confined to utility and exploration, evidenced by several scattered Test Wells and a solitary Jeep Trail winding through the sand.
