Au cours de la matinée matinale de la vapeur, la vapeur sort de la cheminée. En raison de cet effet étrange, les habitants l'ont appelé le Devils Den. Toute l'année, l'eau est limpide et les températures atteignent 72 degrés. Apportez vos amis et votre famille à cette merveille naturelle. Tous les plongeurs doivent être certifiés Open Water, signer des mises en chantier, avoir une formation adéquate et respecter les règles et les règlements.


L'une des principales routes pour rejoindre Devils Den est typiquement la route 27 des États-Unis. Vous trouverez le repaire juste au sud de North East 55th Street.


Devil's Den is formed by a karst window, in which the roof over a subterranean river has collapsed, exposing the water to the open surface, near Williston, Florida. It is privately owned, and operated as a SCUBA diving training and recreational facility.

The water in the underground river is a constant 72 °F (22 °C) degrees. In cold weather water vapor rising from the surface of the river forms a visible plume above the entrance to the cave, which suggested a chimney from Hell to early settlers. The opening to the surface was originally a small solution sinkhole, through which visitors had to squeeze to reach the water. The opening was enlarged in the 1990s to ease access. The cave expands below water level (a shape described as an "inverted mushroom") to up to 200 feet (61 m) across. The maximum depth of the cave reaches 54 ft/16.5 m with the surface diameter being 120 ft. The water level in the cave has fallen along with the water table in the area. However, as of 2018 the water level has risen above the main stage/platform. The cave was opened to the public as a dive site in the early 1990s.

Four underwater passages extend from the pool under the opening, from 5 feet (1.5 m) to 90 feet (27 m) under the surface of the water. The passage called chamber 3, 70 feet (21 m) under water, contained animal and human remains and artifacts. The animal remains, which appeared to be associated with the human remains and artifacts, were from extinct (Pleistocene) species, including mastodons, ground sloths, camels, horses, dire wolves, bog lemmings, Florida spectacled bears, saber-toothed cats, and peccaries. The human remains have been dated to about 7,500 BC.
