What causes the bubbling in the Lake Pit?
The bubbles seen in the Lake Pit and at other pit sites are composed of methane, commonly called as natural gas, escaping into the atmosphere. Methane gas, which is colorless and odorless, is the same substance used in gas-burning home appliances (the gas company adds an odor for safety reasons). Methane is a by-product created when plant and animal remains decompose with the formation of crude oil. The “rotten egg” odor is hydrogen sulfide, another by-product of decomposition.
