About this map

St Marks National Wildlife Refuge dominates the southern landscape of this 1980s orthophotomap, where the border between Wakulla and Jefferson Counties cuts through a dense, hydrologically complex wilderness. The terrain is defined by its karst topography, featuring numerous specialized drainage points such as Bear Bay Sink, Indian Camp Sink, and Pinhook Sinks. These natural depressions, alongside named water bodies like Jake Hole and Big Rock Sink, reveal the underlying limestone geology that shapes the Gulf Coastal Lowlands.

Surface water moves through a network of sluggish drainages including Henderson Slough, Cane Creek, and Gum Creek, eventually feeding into the massive Gum Swamp and the Pinhook River. Distinctive upland and wetland pockets like Smoky Hammock and Featherbed Bay break the saturated landscape, providing crucial reference points in an area largely devoid of permanent human settlements but rich in ecological diversity. The use of aerial photography over-laid with topographic data captures the intricate texture of the Sand Hills and the winding course of the East River.
