PITTSBURG, N.H. (AP) – Two snowmobilers were rescued after their snow machines went through the ice at Lake Francis State Park.

Fish and Game officers said they were checking on some ice fishermen Saturday afternoon when a man ran up to them and said his friend had gone through the ice. Using an inner tube and a rope, the conservation officers and other snowmobilers rescued Joseph Fiorello, 21, of Woburn, Mass.

The conservation officers were warming Fiorello up inside a state park building when they saw a large group of snowmobiles approaching. They tried to warn the drivers away from the weak ice, but one machine went through.

Ronald Piazza, 68, was taken to Upper Connecticut Valley Hospital in Colebrook to be checked for hypothermia, Fish and Game officials said. He was treated and released, a nurse said Sunday.

Piazza’s hometown was not available, but authorities said they believe he lives in Massachusetts and has a camp in the Pittsburg area.

Fish and Game officials warned that this winter’s warm temperatures have left the ice thin on many lakes and ponds, especially where streams or brooks flow into them. The area where the snowmobiles went through the ice was where the Connecticut River flows into Lake Francis.
