Ruby Falls - Underground Waterfall
Ruby Falls is a 145-foot high underground waterfall
located within LookoutMoutain, near Rock City and Chattanooga,Tennessee in the
United States.The cave which houses Ruby Falls was formed with the formation of
Lookout Mountain. About 200 to 240 million years ago (in the Carboniferous
period, at the end of the Paleozoic era) the eastern Tennessee area was covered
with a shallow sea, the sediments of which eventually formed limestone rock.
About 200 million years ago, this area was uplifted and subsequent erosion has
created the current topography. The limestone in which the cave is formed is
still relatively horizontal, just as it was deposited when it was below sea
level.
The Lookout Mountain Caverns, which includes Ruby
Falls Cave, is a limestone cave. These caves occur when slightly acidic
groundwater enters subterranean streams and eats away at the relatively soft
limestone, causing narrow cracks to widen into passages and caves in a process
called chemical weathering. The stream which makes up the Falls entered the cave
sometime after its formation.
The Falls are located at the end of the main
passage of Ruby Falls Cave, in a large vertical shaft. The stream, 1120 feet
underground, is fed both by rainwater and natural springs. It collects in a pool
in the cave floor and then continues through the mountain until finally joining
the Tennessee River at the base of Lookout Mountain.While Ruby Falls Cave
combines with Lookout Mountain Cave to form the Lookout Mountain Caverns, the
two caves were not actually connected by any passage. Ruby Falls Cave is the
upper of the two and contains a variety of geological formations and curiosities
which Lookout Mountain Cave does not have.
Electric lights were installed in the cave, making
it one of the first commercial caves to be so outfitted. Motorists travelling on
I-75 in the 70's were subjected to dozens - maybe hundreds - of billboards along
their route with the words "VISIT RUBY FALLS" beginning hundreds of miles north
and south of the falls itself. Ruby Falls remains a staple of Chattanooga
tourism, operating daily. Ruby Falls is owned by the Steiner family of
Chattanooga, Tennessee.
