In the late 1930s and early 1940s, several auto camps existed along Arizona Avenue between Frye and Ocotillo Roads. These auto camps provided shelter for laborers during the cotton harvest. Some of the camps were operated by landowners and cotton growers themselves. Other were established by entrepreneurs who saw opportunity in the influx of travelers as people migrated from the Dust Bowl region toward California. Lange captured a couple of these locations and recorded the details of rent, facilities, and personal journeys in her captions.
