The Mysterious Life of Caves Notes from Winter 2014
January 7th/ 2014
Kane Cave- has hydrogen sulfide fumes
3 spring fed pools
Rare microbial world (trillions together)
Blue, orange, and black colonies of bacteria found in the caves
Once earth was covered by these bacteria, but predators wiped them out
Bacteria don’t use carbon from trees (no sunlight) they eat chemicals
Bacteria are pretty acidic as well
Did bacteria form the cave or not? Or is it just a favorable habitat for the
microbes? Scientists are still debating on that topic
Limestone chip-several months, bacteria caused erosion but exposed to water so
not much changed
Sulfuric acid is a chemical that metabolized bacteria in a Lower Kane Cave
