About this map

Loxahatchee National Wildlife Refuge dominates this orthophotomap, showing the intricate textured surface of the northern Everglades as it appeared in 1970. This area, also designated as Conservation Area No 1, is characterized by an expanse of sawgrass and sloughs, punctuated by elongated tree islands known as teardrop hammocks. These natural patterns are starkly interrupted by the rigid engineering of the L-40 Canal, which forms a sharp boundary between the protected wetlands and the emerging agricultural or developed lands to the east.

Water management infrastructure is prominent along this border, with several Pumps and a single Pump positioned to control the flow between the marsh and the canal system. The use of aerial photography rather than traditional topographic lines emphasizes the organic, shifting nature of the wetland ecology against the geometric precision of the Florida canal network, documenting a critical era in the state's hydraulic history.
