1972 Map of Sawyer Key

About this map

The Great White Heron National Wildlife Refuge dominates this marine-focused orthophotomap, which utilizes aerial imagery from 1970 to document the intricate shallow-water environments of the Florida Keys. Unlike traditional line maps, this survey uses photographic layers to show the shifting shoals and submerged banks within the Gulf of Mexico. The southwestern corner reveals the small, mangrove-lined landmass of Sawyer Key and the adjacent Riding Key, while the southeastern edge identifies the northern portion of the National Key Deer Refuge near Crane Key. These protected waters are bisected by the Intracoastal Waterway, a vital transit corridor for local mariners navigating through the Cudjoe Channel. The map specifically notes an Indefinite Boundary throughout the area, reflecting the complex and ever-changing nature of these coastal Florida jurisdictions and shorelines.
