オキーチョビー湖
Fort Center is in the Lake Okeechobee Basin, an area that surrounds and drains into Lake Okeechobee, and is synonymous with the Belle Glade culture area, one of several related culture areas in southern Florida. The Kissimmee River valley is usually regarded as a sub-area of the Lake Okeechobee Basin (Belle Glade culture area). Sears treats the Lake Okeechobee Basin, including the Kissimmee River Valley, as a sub-region of the Glades culture area, while others place the Belle Glade (Lake Okeechobee) and Glades areas on an equal footing. The cultural traditions of southern Florida had a long history and were well adapted to the area. Archaeological evidence of changes in those cultures is mostly limited to small changes in the few ceramics that were decorated.
