1956 Map of Durmid

USGS Topo · Published 1979

About this map

The eastern shore of the Salton Sea dominates this mid-century survey, revealing a landscape defined by the arrival of infrastructure in a harsh environment. The Southern Pacific railroad runs parallel to the waterline, serving small outposts and industrial points like Ferrum, Durmid, and Bertram. These settlements, often consisting of little more than sidings or depots, supported the local extraction economy, most notably seen at the Bertram Mine situated near the Imperial County line.
