The shaft leads into a place deeper inside where researchers recently found six unique strains of bacteria living in a bed of pink slime that are part of a little-understood biochemical cycle that devours iron, produces sulfuric acid, and creates a nightmarish broth of copper, zinc and arsenic.
There, the chemical reactions drive temperatures up to 130 degrees and the puddled water is sulfuric acid, concentrated enough to melt an aluminum ladder. Sugarek said the rocks inside this noxious horror house have been known to catch on fire from time to time.
