1940 Map of Iris

USGS Topo · Published 1956

About this map

The Southern Pacific railroad corridor anchors the desert landscape of this 1940 survey, connecting isolated stops like Iris, Tortuga, and Amos along the edge of the Chocolate Mountains. This arid terrain stands in stark contrast to the emerging agricultural grid in the southwest corner of the map. Here, water infrastructure including the East Highline Canal and the Alamo River facilitates a dense network of farm roads named for botanicals, such as Magnolia Road and Narcissus Road.
