STS062-153-146 Northeast Florida, U.S.A. March 1994 Northeastern Florida is a land bridge between the Atlantic Ocean (top) and the Gulf of Mexico (bottom right). In addition to three of Florida's popular cities--Jacksonville (upper left), Clearwater, and Tampa (barely discernible along middle right)--several natural features are apparent--north-flowing Saint Johns River south of Jacksonville; numerous oval karst lakes with sunglint, which helps identify scattered lakes throughout north-central Florida; large Okefenokee Swamp of southeast Georgia with a small section in Florida northwest of Jacksonville; and the Gulf of Mexico surrounding the delta of the winding Suwanne River (near bottom center). Because this is an area of very low relief (relatively flat topography near sea level), most of the densely vegetated areas are swamplands. Scattered cumulus clouds are apparent in the upper right corner.
