1932 Map of Barstow

Settlement patterns in the early 1930s remain closely tied to the railroad and the river, with Barstow emerging as a primary hub. Small communities and stops like Oro Grande, Helendale, and Hodge highlight the era's reliance on rail transit and riparian access. Industrial activity is evident in the presence of the Apex Mine and Western States Mine, while more isolated outposts like Las Cruces Ranch and Adelanto suggest the slow expansion of agricultural and ranching efforts into the surrounding desert.
