Threemile Island sits within this portion of Collier County, which is defined by the intricate hydrology of the western Everglades region. Surveyed by the U.S. Geological Survey in 2012, the landscape is dominated by complex watercourses and wetlands characteristic of the Florida interior. The cartography emphasizes the natural drainage patterns of this marshland environment, where small hammock-like islands provide subtle vertical relief amidst the surrounding wetlands. This digital-age survey captures the pristine state of the area’s hydrography, revealing the subtle ways land and water intertwine in this ecologically critical corner of the state.
