About this map

The Colorado River and Gila River converge at the heart of this 1905 survey, illustrating a critical junction of water and rail transport at the dawn of the 20th century. This arid landscape is defined by the heavy infrastructure of the Southern Pacific railroad and the early irrigation efforts of the Imperial Canal. The town of Yuma serves as a central hub, surrounded by outlying agricultural and mining developments such as Somerton, Yuma Heights, and the Yuma Indian Reservation.

To the north and west, the terrain rises into the Sand Hills and mountain peaks where industrial activity is marked by the American Mine and Picacho Mine. The mapping of international and state boundaries, including the line between United States and Mexico and California and Baja California, highlights the strategic importance of this borderland region. Traces of early settlement appear at Ogilby and Hedges, while specialized landmarks like the Yuma School and Gold Rock Pump provide granular detail for local history research.
