2018 Map of Long Island Marsh SE

About this map

Long Island Marsh and the surrounding wetlands of the Florida interior define this landscape where Charlotte, Highlands, DeSoto, and Glades counties meet. The area is characterized by a complex network of seasonal watercourses and drainage features, including the winding Tippen Bay, Gator Branch, and Joe Slough. Human activity is primarily centered on ranching and aviation, most notably at the Montgomery Ranch Airport located near SE Betty Dr. The map illustrates a transitional environment where traditional land use and natural hydrology intersect, preserved in a network of named grades and rural roads such as Lott Grade and John Pierce Grade Rd. These routes often follow the high ground between swampy depressions like Gannet Slough, reflecting the historical challenge of navigating this corner of the state.
