1982 Map of Dog Island

About this map

Dog Island serves as the focal point of this 1982 orthophotomap, showing the barrier island's vegetation and shifting sands during the early 1980s. This hybrid topographic-bathymetric study captures the complex maritime environment where Saint George Sound meets the Gulf of Mexico. On the island's northern shore, Tysons Harbor provides a sheltered inlet, while the surrounding waters are defined by hazards such as Lanark Reef and the extensive Dog Island Reef. A notable Ferry route is indicated, connecting the island to the mainland across the sound. Frequent shoreline shifts are explicitly noted as an area subject to frequent change, reflecting the dynamic nature of these coastal landforms before subsequent decades of storm-driven erosion and deposition further altered the landscape.
