1957 Map of Long Island Marsh NE

About this map

Cow Slough winds through the southern reaches of this interior Florida landscape, marking a terrain defined by wet prairies and seasonal marshes. The boundary between De Soto and Highlands counties bisects the northern half of the survey, where the land transitions from open wetlands into areas delineated by long Fence Lines. This 1957 topographic study, photorevised in 1972, reflects the sparse, rural nature of the region before significant drainage or modern development altered the hydrography. The map provides a clear view of the natural water distribution and the simple survey lines that governed land use and cattle ranching in the mid-20th century.
