Cannon Mountain in the White Mountains of New Hampshire is forging ahead with its Mittersill expansion.

The most recent work was installing 13 7,000-pound lift towers with the help of a helicopter.

John DeVivo, the general manager of Cannon Mountain and the surrounding Franconia State Park, said, "It's taken a whole lot of planning-and a Sikorsky S61 helicopter-to place the towers for the new double chairlift on Mittersill, as well as the lift's 7,500-pound bull wheel and mountaintop lift shack."

It's the second time the helicopter has been called into action.

"Back in September, the helicopter transported concrete from a truck at the base to the concrete forms on the mountain so that footings for the new towers could be created," DeVivo said. "It was quite a sight: A bucket holding one-and-a-half yards of concrete, weighing 3 tons, was attached by a line to the chopper and carried up the mountain. Once all the concrete was poured - it took a total of 70 round trips - the chopper flew out the old towers."

Once work on the new double chairlift is complete, Mittersill will be able to offer lift-served skiing and boarding for the first time in nearly 30 years.

DeVivo said he expects the lift will open for skiers and snowboarders in January 2011 and then run every day during the season that Mittersill is open and skiable.

The project is part of Phase II in a three-year, $4 million investment and improvement campaign at Cannon.

Mittersill offers 86 acres of steep, narrow, and 100 percent natural terrain.

DeVivo describes it as "one large gladed area."
