About this map

Long Island Marsh and a complex network of wetlands dominate this South Central Florida landscape, where the borders of Highlands, DeSoto, Charlotte, and Glades counties converge. The terrain is defined by seasonal water flow through features like Rainey Slough, Joe Slough, and Gannet-Slough, alongside the meandering Gator Branch and Tippen Bay. Human imprint on the land is marked by isolated ranch infrastructure and private airfields, most notably the Montgomery Ranch Airport located in the western portion of the quadrangle.

Transportation through these flatlands relies on a few primary arteries such as State Hwy 731 and a series of rural routes and grades, including Lott Grade and John Pierce Grade Rd. The rectilinear property lines of the Public Land Survey System stand in sharp contrast to the irregular, fluid boundaries of the marshes, illustrating the intersection of modern land management with an ancient hydrological system.
