About this map

Saint Catherines Island and its surrounding tidal landscape dominate this contemporary coastal survey, where the Atlantic tides meet a complex network of salt marshes and rivers. The Intracoastal Waterway threads through the sounds and creeks, passing landmarks like Middle Ground and Walburg Island. On the mainland, the Harris Neck National Wildlife Refuge preserves a significant portion of the riverine environment near the Mollclark River and the South Newport River.

Settlement is concentrated at Colonels Island and Yellow Bluff, where a modest network of local roads such as Oyster Point Dr and Lake Pamona Dr reach toward the water. This environment is defined by its hammocks—elevated ground such as McQueen Hammock and Black Hammock—which provide stable footing amidst the wetlands. The confluence of the Medway River and Sunbury Creek highlights the historic maritime routes that have shaped this Georgia coastline for centuries.
