Pelican Dolphins swim in the estuaries where coastal rivers merge with the ocean. Native Americans navigated the Satilla long before the discovery of America. Coastal Plain streams are characterized by clear, clean “blackwater.” The dark tea color comes from tannic acid in decaying riverbank vegetation. American explorer and naturalist William Bartram visited the Satilla basin during his exploration of the American Southeast in 1775 and 1776. A combination of rivers and ocean, the salt marsh along the Georgia coast is one of the most productive ecosystems on earth. Living plants and animals, as well as dissolved minerals and decaying vegetation, fill the marsh with nutrients. African-Americans celebrate the rich cultural heritage of the coastal rivers and barrier islands through crafts, books, music Loggerhead turtles nest and educational tours. on beaches near the mouths of coastal rivers. Recreational fishermen cast for shrimp in the tidal creeks at the mouth of the Satilla.
