Cave Of Swallows

November 3, 2011 by staff 

Cave Of Swallows, The Cave of Swallows, also called Cave of the Swallows (Spanish: S?tano de las Golondrinas), is an open air pit cave in the Municipality of Aquism?n, San Luis Potos?, Mexico. The elliptical mouth, on a slope of karst, is 160 by 205 feet (49 by 62 m) wide and is undercut around all its perimeter, further widening to a room approximately 995 feet (303m) by 440 feet (135m) wide. The floor of the cave is a 1,094-foot (333 m) freefall drop from the lowest side of the opening, with a 1,220-foot (370 m) drop from the highest side, making it the largest known cave shaft in the world, the second deepest pit in Mexico and perhaps the 11th deepest in the world. A skyscraper such as New York City’s Chrysler Building could easily fit wholly within it.

Opened up by water erosion in a fault on an impermeable limestone plain and with a roughly conical shape, the cave has been known to the local Huastec people since ancient times. The first documented exploration was on 27 December 1966 by T. R. Evans, Charles Borland and Randy Sterns.
