2012 Map of Content Keys

About this map

Gulf of Mexico waters surround this intricate archipelago in Monroe County, where the transition from shallow banks to deeper navigable channels defines the local maritime geography. The Content Keys and Water Keys form a complex network of landmasses separated by the Content Passage, illustrating the delicate shoreline of the Florida Keys. To the east, larger features like Big Spanish Key and Howe Key are documented alongside specialized environments such as the Howe Key Mangrove and Little Spanish Key Mangrove. This coastal survey also identifies numerous underwater hazards and landmarks, including Turtlecrawl Bank, Cutoe Bank, and the Spanish Banks. These features, along with the Harbor Channel, provide essential context for understanding the historic and natural navigation routes through these low-lying islands.
