About this map

Everglades National Park encompasses this intricate marine landscape within Florida Bay, where a dense network of mangroves and shallow shoals defines the region's geography. This orthophotomap, based on 1971 aerial photography, provides a clear view of the complex waterway systems such as Whipray Channel and Jimmie Channel. These channels weave between clusters of islands including the Calusa Keys, Buttonwood Keys, and the Bob Allen Keys.

The map reveals the specific layout of named islands that have long served as landmarks for mariners and local fishermen, from the northern Samphire Keys down to Captain Key and the Pollock Keys in the south. The hydrographic data and soundings included here reflect the delicate balance of this subtropical wilderness before more modern environmental changes, offering a precise look at features like Russell Key and the Blackwater Keys as they appeared in the early 1970s.
