The Great White Heron National Wildlife Refuge encompasses a vast marine and island landscape within the Florida Keys, characterized by intricate mangrove systems and shallow tidal basins. This modern survey illustrates the complex geography of the Snipe Keys and Mud Keys, highlighting the narrow passages that define navigation in these waters, such as the Outer Narrows and Mud Key Channel. To the south and west, the map details numerous named features like Cayo Agua and the Lower Harbor Keys, which sit near the broader Jewfish Basin. The placement of landmarks like Old Dan Mangrove and Fish Hawk Key reflects a coastal environment shaped by historical naming conventions and ecological preservation, situated just off the Intracoastal Waterway.
