Lechuguilla Cave

Lechuguilla Cave is, as of February 2012, with 134.6 miles (216.6 km) the seventh-longest explored cave in the world and the deepest in the continental United States (1,604 feet or 489 meters), but it is most famous for its unusual geology, rare formations, and pristine condition.

The cave is named for Agave lechuguilla, a species of plant found near its entrance. Lechuguilla is in Carlsbad Caverns National Park, New Mexico. Access to the cave is limited to approved scientific researchers, survey and exploration teams, and National Park Service management-related trips.

Famous quotes containing the word cave:

    “The use of symbols has a certain power of emancipation and exhilaration for all men. We seem to be touched by a wand, which makes us dance and run about happily, like children. We are like persons who come out of a cave or cellar into the open air. This is the effect on us of tropes, fables, oracles, and all poetic forms. Poets are thus liberating gods.”
    —Ralph Waldo Emerson (1803–1882)
