1958 Map of Mount Wrightson

About this map

Coronado National Forest dominates this mid-century view of the Santa Rita Mountains, where the landscape is etched with the remnants of late-19th and early-20th-century mining efforts. The map documents the scattered Alto (Site) and several historic cattle operations like Salero Ranch and Weatherhead Ranch. Mineral exploration is represented by an extensive network of claims including the Helvetia Mine, Eureka Mine, and the Montosa Mine, many of which were accessed by rugged jeep trails. The southern portion of the quadrangle shows the distinctive Luis Maria Baca Grant (Float No 3), a significant Spanish land grant legacy. Transportation and cultural history are marked by the San Jose Railroad Grade and a petroglyph near the San Cayetano Mountains, indicating centuries of human presence from indigenous peoples to railroad engineers.
