PITTSBURG, N.H. (AP) – At least three snowmobilers were injured in accidents in the North Country this Presidents Day weekend.

Two state conservation officers rescued a snowmobiler after his machine plunged into Lake Francis in Pittsburg Friday night. The men pushed a canoe to the snowmobiler, Todd Bergeron of Troy, who was clinging to the ice’s edge about 40 yards from shore.

“He was saying he couldn’t hang on anymore,” New Hampshire Fish and Game conservation officer Adam P. Cheney said.

As soon as Bergeron, 39, grabbed onto the canoe’s side, Cheney and officer Jeremy Hawkes pulled him back to shore. Bergeron suffered hypothermia, and couldn’t stand or move when the officers got him out of the water, Cheney said.

The Pittsburg rescue squad later took Bergeron to Upper Connecticut Valley Hospital in Colebrook.

Bergeron was one of three Troy men riding snowmobiles across the lake when they hit thin ice, Cheney said. The lead driver, Joseph Giguere, 48, barely made it safely across. Next came Stephen Brumaghim, 42, whose snow machine broke through the ice and plunged into the water. He managed to swim safely to shore.

Cheney said the men were not skimming, or riding snowmobiles over water.

Bergeron and Brumaghim hired a private company to pull their snow machines from the water, Cheney said.

On Saturday, a Peterborough man suffered a broken leg when two snowmobiles collided on Trail 112, about six miles off Route 3 in Pittsburg, Pittsburg Police Chief Richard E. Lapoint said.

Four snowmobilers were riding the trail about 1:30 p.m. when mechanical problems forced the lead driver to slow down, Lapoint said. Michael Ruthier, 46, of Peterborough, slid into his machine from behind, pinning his leg, the chief said.

Officials took Ruthier to Upper Connecticut Valley Hospital with a broken leg, Lapoint said.

Later Saturday, a Bow man lost control of his snowmobile in Pittsburg, Lapoint said.

Douglas Wheeler, 54, went off the trail about 5:40 p.m. and struck a tree, Lapoint said. He suffered a broken leg and internal injuries.
