I have a hole in the ice in my lake, about 2 foot across. There are bubbles in the middle of this hole. The hole is in front of the dam about 20 feet. What kind of gas would be coming through the ice. The water is 5 to 7 feet deep in this area and the ice looks like it could be 3 inches thick. It has made a crater type ridge maybe 1 inch tall around this hole. 8 year old lake. There is water at the lakes bank so I am not going on the ice. Would like to cover with plastic and light it to see if it is meathain. Last week there were 6 or 7 smaller holes on the other side. looked like ice auger holes but had 5 or 6 jagged cracks coming off the round holes. These holes were 7 feet from bank in 6 to 7 feet of water and did not see any air bubbles coming from them. In the summer there are bubbles coming off the bottom but not as many and in a different spot. Any idea what this could be? When we were drilling a well. The drill bit dropped 12 to 15 feet like it hit a hole. Could there be a cave under ground that air is being forst out of it as water fills it?
Anyone else have these holes in there ice?
