1970 Map of Grassy Marsh

About this map

Grassy Marsh dominates this 1970 orthophotomosaic, revealing a landscape defined by the transition from natural wetland to managed agricultural land. In the northern sections, systematic grid patterns and infrastructure like a Radio Tower and multiple Pump stations signal the encroachment of drainage and cultivation into the interior. These features reflect the mid-century effort to reclaim Florida's interior wetlands for productivity, with dikes and canals cutting through the native vegetation. Further south, the terrain reverts to the intricate, organic patterns of Collins Slough, where water-carved channels and scattered cypress heads create a complex mosaic of sawgrass and sloughs. This aerial perspective documents the precise boundary where mechanical land management meets the native hydrological systems of Hendry County during a period of rapid environmental modification.
