Mysterious Rings Found In Canadian Forests

Only seen from the sky, hug rings or circles in the trees. Thousands of large, perfectly round circles. Space ships landed here or are these the same as crop circles only in trees?

No it is believed that the strange circles are being caused by "giant, natural electrochemical cells — big centres of negative charges called reduced chimneys — that are frequently situated over metal or mineral deposits, or methane." It seems finding the circles gives clues that there something worth digging for, possible metal, minerals or more important alternative fuel in the form of methane. With the cost of oil going up alternative fuels are going to be even more valuable resources so I guess it is a good thing someone figured out that the rings may mean dig here. I found the article on the Mysterious Rings Found In Canadian Forests on the CBC web site. It is interesting but I pulled some of the pictures and info for a quick overview. The article is still worth reading though.
