A missing teen was found alive and well after two days alone at Maine's Sugarloaf ski resort Tuesday.

The 17-year-old, Nicholas Joy of Medford, Massachusetts went missing Sunday afternoon on a ski trip with his father Robert Joy as they took separate trails from the top and son failed to show up at the bottom.

Joy was found after two nights by a snowmobiler not part of the official search party found him Tuesday morning on a trail off the western side of Sugarloaf Mountain.

The teen was taken to Franklin Memorial Hospital in Farmington for evaluation, said Lt. Kevin Adam, the search coordinator.

It turned out Joy ventured off his trail inadvertently down the west side before realizing that he couldn't make it back to ski trails, Adam said.

The search was confined as weather conditions were bad and had to be suspended Sunday and Monday nights, remarkably the boy survived by building a mount of snow that he used as shelter.

Joy is doing well in "remarkably good shape" despite the fact that he was lost outside in the snow for two days. Also the fact that the winds weren't that strong up on the mountain where he was found was helpful.

"But he did the right thing in building a snow cave, and obviously he's still alive to talk about it, so he made some good decisions," Adam said.

Sugarloaf general manager John Diller said, "Evidently, he watches those survival shows. We were ecstatic. I was with his parents about a minute after they found him. I cried along with them."

Joel Paul, a volunteer fire captain from Warwick Massachusetts, found the boy, the warden service said.
