Northwestern Ontario Stromatolites

Fossilized stromatolites can be found in a few locations northwestern Ontario. The fossilized stromatolites in the bedrock along the shore of Lake Superior between Rossport and Schreiber, Ontario are over two billion years old. A recent article about these stromatolites can be found in the November 2009 issue of Lake Superior Magazine. A less extensive, but easily accessible fossilized stromatolite, can be seen in a rockcut near Kakabeka Falls, Ontario
