A giant spinning wheel of ice on the surface of the Presumpscot River has enthralled crowds in Westbrook, Maine since Monday, January 14, 2019. Many locals have likened it to crop circles –strange patterns that appear mysteriously overnight in farmers' fields, which have long been theorized to be markers of extraterrestrial communication – and speculated that the icy ring is a landing site for an alien ship. Unfortunately for UFO enthusiasts, experts say that the rare winter phenomenon is a natural occurrence.
