Cueva de Villa Luz
From Wikipedia, the free encyclopedia
Cueva de Villa Luz (Cave of the Lighted House) is a cave near Tapijulapa in the southern Mexican state of Tabasco. Its thermal sulphur springs produce a rotten-egg smell, and bacteria thrive on the resulting hydrogen sulfide gas. These sulfur springs bubble hydrogen sulfide gas through the water, dyeing it white with sulfuric acid. Its 2 kilometers maze of passages is etched out of Cretaceous limestone by sulfuric acid and bacteria.
The cave was first explored and documented by Dr. Jim Pisarowicz in 1986. The cave contains formations called “snottites” because of their mucus-like resemblance to stalactites, and potentially lethal levels of hydrogen sulfide gas.
