Während der kühlen frühen Morgen steigt rauchähnlicher Dampf aus dem Schornstein. Aufgrund dieser unheimlichen Wirkung nannten die Einheimischen die Devils Den. Das ganze Jahr hindurch ist das Wasser kristallklar mit Temperaturen von 72 Grad. Bringen Sie Ihre Freunde und Familie zu diesem Naturwunder. Alle Taucher müssen Open Water zertifiziert sein, unterzeichnen Freigabe, haben eine ordnungsgemäße Ausbildung und befolgen Regeln und Vorschriften.
Einer der primären Routen, um die Devils Den zu erreichen ist in der Regel North US Highway 27. Sie finden die Höhle nur südlich von 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.Provided By: https://en.wikipedia.org/wiki/Devil%27s_Den_Cave
