GORHAM, N.H. — A skier suffered a life-threatening leg injury after triggering an avalanche while skiing down Mount Washington, the highest peak in the Northeast, New Hampshire Fish and Game conservation officers said.

Dominic Torro, 30, of Bow, New Hampshire, was coming down Airplane Gully in a wilderness area with a friend Saturday morning, Sgt. Glen Lucas of the department said in a statement.

Torro’s friend and another skier went to Torro and called 911. No one else was caught in the avalanche.

Authorities worked on a rescue plan for a National Guard helicopter and the Mount Washington Auto Road Sno-Cat vehicle.

“Concern about specific and needed medical action rose to the level that a joint phone call was made to a highly experienced back country paramedic in order to give medical guidance to the two skiers giving the aid,” Lucas said. “The guidance was given and Torro was stabilized.”

While waiting for the helicopter, the skiers shoveled out an area on the slope so that a paramedic and litter basket could be lowered down from the helicopter and have enough room to load Torro and hoist him back up.

Torro was taken to Dartmouth-Hitchcock Medical Center in Lebanon. A message seeking his condition was left with a spokesperson Monday.

Mount Washington is 6,288 feet tall. The Mount Washington Avalanche Center said it is currently in a general advisory period, not yet in a daily hazard rating.
