A 70-year-old man died Sunday after the truck he was riding in fell through the ice at a pond in Moultonborough, authorities said. The New Hampshire Fish and Game Department said it was notified shortly before 8:30 a.m. that a vehicle had gone through the ice at Berry Pond. The driver was able to exit the truck, but a passenger did not escape, the agency said. Rescue workers responded to the scene and recovered the man’s body around noon. His identity was not immediately released. Both men were experienced at traveling on ice and were familiar with the pond, but rapid changes in the weather recently led to variable ice conditions statewide, the fish and game department said. Both men were members of the Lakes Region Racing Club, which holds auto races on the ice during the winter, WMUR-TV reports. Authorities said it appears they were assessing the depth of the ice when the truck fell through.
