About this map

The Magma Arizona railroad and utility infrastructure dominate this Pinal County landscape, reflecting the mid-century industrial development of the Sonoran desert. The small settlement of Magma serves as a focal point at the junction of the Southern Pacific line, characterized by a Water Tank and nearby surveying benchmarks. Away from the rail corridors, the terrain is marked by intermittent drainage from Queen Creek and isolated outposts like Ellsworth Ranch.

Modern transport and energy footprints are evident in the numerous easements, including a Power Line, Telephone Line, and a Pipeline that traverse the quadrangle. The map also documents early aviation facilities, such as the designated Landing Field and a separate Landing Strip, illustrating how this transition zone between mountains and basin served as a hub for both terrestrial and aerial transit.
