1974 Map of California Slough

About this map

Big Cypress National Preserve occupies much of this Florida landscape, captured through orthophotography and planetable surveys in the early 1970s. The terrain is characterized by the intricate patterns of Doctors Prairie and the eponymous California Slough, showing the complex hydrology of the region before further modern development. Man-made interventions are starkly visible against the wetlands, specifically the Everglades Parkway (Toll Road) cutting east-to-west and the Levee 28 Interceptor Canal running along the eastern boundary. This boundary also serves as the divide between Collier and Broward counties, providing a clear look at how infrastructure was used to manage the swamp environment. A single Pipeline route further illustrates the mid-century industrial footprint within this protected ecological area.
