A couple of years ago, I heard of a case where a guy was flying a small plane over James Bay in Québec in around 1978 and he saw what he thought were 5 fuel tanks on the ground, around 60' in diameters each. He said this was strange since this is in the middle of nowhere and these weren't even there a couple of days before and no road is leading to this place.
