About
Dismal Key is a small island, part of the Ten Thousand Islands archipelago in the Gulf of Mexico off the coast of Florida. The island is artificial, constructed by people of the Glades culture. Construction of the island proceeded in stages over some 1,500 years following the end of the Archaic period in Florida. Occupation probably ended a couple of centuries before the arrival of Europeans in Florida. Dismal Key was occupied by several hermits in the 20th century.
