About this map

Jewfish and Anglers Park sit at the critical land-and-water junction where the Upper Keys meet the mainland marshes. This survey details the complex network of sounds, passes, and human engineering that defines the northern entry to Key Largo. The Overseas Hwy serves as the primary spine of the landscape, crossing Jewfish Creek to connect the island chain with the mainland across Cross Key.

The presence of Everglades National Park covers the western half of the map, preserving the delicate transition between the mangroves and open waters like Blackwater Sound and Florida Bay. Of particular interest to local historians is the Marvin D Adams Waterway, a significant cut providing passage between Blackwater Sound and Largo Sound. The map also captures numerous named keys and points, such as Shell Key and Snake Point, alongside biological features like the Cormorant Rookeries in Manatee Bay.
