Brian>>Just wanted to delurk for a moment to say I agree that it is
extremely unlikely to be a meteor.
However, I don't think it's CO2 gas either. There would have to be
a source of CO2 gas (usually volcanic) and the lake would have to
be deep enough to 'cork' the bottle with hydrostatic weight. For
specifcs please see this webpage about the Lake Nyos disaster at:

I find the methane gas release or the fish school idea plausible.<<
Okay Brian...I looked over the website you provided and I gather you agree
with me about the disaster in Cameroon being CO2 gas, but the incident in
michigan perhaps being methane gas or school of fish? A reasonable
possibility....perhaps a better possibility than the CO2 gas?

Overview from the website
In 1986, a tremendous explosion of CO2 from the lake Nyos, West of Cameroon,
killed more than 1700 people and livestock up to 25 km away. The dissolved
CO2 is seeping from springs beneath the lake and is trapped in deep water by
the high hydrostatic pressure. If the CO2 saturation level is reached, bubbles
appear and draw a rich mixture of gas and water up. An avalanche process is
triggered which results in an explosive over-turn of the whole lake. Since
1990 a French team has carried out a series of tests in an attempt to release
the gas slowly through vertical pipes …
