About this map

The United States Mexico Arizona Sonora Boundary Line anchors the southern edge of this tactical survey, highlighting the international frontier in the years before the Second World War. The landscape is dominated by the massive landholding of the San Bernardino Grant and a network of remote family cattle operations. Water security is the primary concern of the region, evidenced by the numerous reservoirs, wells, and cisterns supporting the Slaughters Ranch San Bernardino and the Bar M Ranch (South).
