These stone formations are called INUKSHUK

During our drive from Fort Frances onto 502 heading towards Dryden in Canada, besides seeing bears sunning themselves on the culverts next to the road and an occasional moose in the bogs, my wife and I would see quite a few rock formations on top of the boulders that are along side of the road. We came to find out that these rock formations are called Inukshuk and the literal meaning is "in the image of man". Here is a great link to read all about them. www.sulis.net/inukshuk.htm
