Wow! How is that even possible? Have people outside of Maine even heard about the Presumpscot River in Westbrook, Maine? I am sure even most people in Maine haven’t heard of it. Well, after you see THIS, you won’t be able to forget. A mammoth frozen disk appeared out of nowhere in the middle of the river. It looks like a perfect circle. It is estimated to be around 100 yards across. An amazing sight, no doubt.
