History
The name "Okaloosa" comes from the Choctaw oka losa, "black water". The Euchees came into the area from the "west" sailing along the coast until "the great spirit told them to stop" in what is now Walton County. They left the Indian Mounds that we see today, one being in what is now downtown Fort Walton Beach. There was even a pirates cove near Mary Esther. Even the notorious pirate LaFitte was said to have docked there.
