A 15-year-old boy died from his injuries after crashing his snowmobile into a tree west of the town of Portage, officials said Sunday.

The teen from Windham, who was part of a group of eight riders, crashed in freezing rain and limited visibility, Lt. Doug Tibbetts said.

Wardens working in the area reported that freezing rain was accumulating on helmet visors and that riders were having to stop to wipe away the ice around the time of the crash, which was reported at 4:12 p.m. Saturday, Tibbetts said.

The teen died Saturday night after being treated at Aroostook Medical Center in Presque Isle and transferred to Eastern Maine Medical Center in Bangor, he said.

Tibbetts declined to release the name of the teen, who was vacationing with his father and stepmother at Portage Lake. Speed and poor visibility were factors in the crash, he said.

It was Maine's second snowmobile fatality this winter. A 19-year-old from Cushing died on Dec. 22 after tumbling into the path of an oncoming car.

There were 12 snowmobile fatalities in Maine last winter.
