Dry Tortugas Blue Water
Blue Water Surrounding Fort Jefferson, Dry Tortugas National Park, Florida
"The first European to discover the islands was Spanish explorer Ponce de León. He gave them the name on his first visit in 1513. The name is the second oldest surviving European place-name in the US. They were given the name Las Tortugas (The Turtles) due to 170 sea turtles taken on the islands and shoals by de León's men. Soon afterward, the word "Dry" was added to the name, to indicate to mariners the islands' lack of fresh water." Wikipedia
