About this map

Long Island Marsh dominates this landscape at the intersection of four Florida counties: DeSoto, Highlands, Charlotte, and Glades. This 1957 survey, later updated with mid-1980s data, illustrates the complex hydrology of the region, where water moves through a network of sloughs and bays. Notable water features including Gannet Slough, Rainey Slough, and Tippen Bay define the natural drainage patterns of the area.

Human activity is marked by the presence of Montgomery Ranch and its associated Landing Strip, reflecting the remote ranching operations common in this part of Florida during the mid-20th century. A significant historical landmark is the Old Railroad Grade that cuts across the landscape, suggesting previous industrial or logging efforts that have since been reclaimed by the surrounding wetlands. This map provides a look at the transition from natural marshland to light agricultural and aviation use before modern developments.
