Florida, as we all know, is a low coastal plain having as its principal element a limestone base, with its share of swamps and soft adhering mud which covers easily and in certain cases preserves. On the east and west coasts the environmental conditions differ from each other and from the peninsula itself, as well as from the entire southeastern area to which anthropologically it belongs, and from the rest of North America. On the western coast are the shell keys and coral reefs and not far distant on the eastern side, in addition to a few reefs, lie the mass of islands of the Bahamas and the Antilles. Indeed it is only forty miles from Gun Keys in the Bahamas to the Florida mainland. Geologically, therefore, with its coral and shell formations, Florida is analogous to the eastern coast of Middle America and to the West Indian inlands.
