A rare incidence of an East Coast treewell submersion is being reported out of Sugarloaf Ski Resort in Maine where a skier was trapped hanging upside down for 45 minutes over the weekend. New Center Maine reports the skier started his run on a double black diamond when he stopped, lost his balance, and fell head-first into the hole. Sugarloaf Ski Patrol responded to the scene and dug the man out who was thankfully uninjured.
