We now know how a Michigan ski instructor died at a Colorado ski resort. Grace McNeal's body was found at the base of a tree at the Steamboat Resort January 6th, where she had been skiing with friends. McNeal was from Cedar and an instructor at the Arapahoe Basin Ski Area. The coroner says she was wearing a helmet and apparently lost control and fell into an area of quicksand-like snow at the base of the tree. She couldn't get out and suffocated.
