1971 Map of Graham Marsh

About this map

Graham Marsh dominates this 1971 orthophotomosaic, revealing the complex hydrological patterns of the northern Everglades before extensive modern alterations. The combination of aerial photography and topographic data illustrates the intricate mosaic of wet prairies and hardwood heads, such as Tom Still Hammock, that characterize the interior of Hendry County. This specific period of the early 1970s shows the landscape in a state of transition, where established natural features like Collins Slough are punctuated by man-made infrastructure like the Lookout Tower near Devils Garden. The map provides a clear record of the seasonal waterflow and vegetation clusters as they existed prior to further development in south Florida.
