NORWAY, Maine — A 40-year-old camp on Pennesseewassee Lake was destroyed by fire Wednesday night but no one was hurt in the fast-moving blaze.

Firefighters from five departments battled the fire on Sandy Shore Lane, struggling to get equipment down the narrow, dead-end camp road.

“Once one truck went in, that was it,” Norway Assistant Fire Chief Jim Tibbetts said. “No one else could get in or out.”

The firefighting effort was mostly about containment. By the time the first crew arrived, the roof was fully engulfed in flames and the rest of it followed soon after.

“It was pretty well gone when we got there,” Tibbetts said.

Nearly two dozen firefighters working from three trucks battled the blaze. Tibbetts said the camp, built in the 1940s, is the summer home of a woman who lives the rest of the season in the town of Paris.

Norway crews were assisted by others from Paris, Oxford, Poland and Waterford. The investigation into the cause of the fire was getting underway later Wednesday night.
