1929 Map of Fortuna

About this map

The Fortuna Mine stands as a focal point in the southern reaches of the Gila Mountains, marking a period of intense mineral extraction in the Yuma region. The landscape is defined by the stark divide between the high peaks of Muggins Mountains and the broad Gila Valley, where the Gila River winds past the Laguna Mts. Transportation and communication infrastructure are central to this 1920s-era survey, showing the Southern Pacific railroad corridor and the Electric Gas and Water Telegraph Line crossing through Telegraph Pass. Small rail-aligned settlements like Blaisdell, Fortuna, and Ligurta serve as the primary human outposts in this desert terrain. The presence of the Tinajas Altas Road and landmarks like Granite Spur and Clotho's Temple reflect the early routes used by surveyors and miners navigating the arid Arizona borderlands.
