2021 Map of Content Keys

About this map

The Content Keys and surrounding shallow banks define this marine landscape in the lower Florida Keys. Navigational corridors like the Intracoastal Waterway and Content Passage provide passage through the complex arrangement of submerged flats and mangrove-fringed islands. The map highlights several distinct keys, including the larger Cutoe Key and the smaller, outlying Annette Key to the southeast. Submerged geography is clearly delineated by features such as Harbor Key Bank, Turtlecrawl Bank, and Spanish Banks, illustrating the intricate seafloor topography that governs movement through these waters. This survey captures the natural boundary between the open Gulf of Mexico and the protected interior channels, documenting the pristine coastal environment as it existed in 2021. The naming of smaller features like Little Spanish Key Mangrove and Howe Key Mangrove points to the ecological sensitivity of this Florida maritime region.
