LINCOLN - A 67-year-old New Jersey man was injured Thursday when he fell about 15 feet from a platform between two zip lines at Loon Mountain Resort.

Molly Mahar, spokesman for the resort, said at approximately 2:10 p.m. a man identified only as a resident of Palisades Park, N.J., was using the resort's zip line. He made it successfully down the first cable from the resort across the North Branch of the Pemigewasset River to the other side, not far from the Kancamagus Highway.

Mahar said the man was unhooked from the line by the attendant, as is the procedure, and directed to exit the area to climb up to a second cable to continue down the next zip line.

For some unknown reason, Mahar said, the man returned to the attendant who twice directed him in the other direction. The man then fell from the platform onto rocks below along the river bed.

He landed on the rocks on his stomach and spun around according to witnesses, Mahar said.

The man was alert after the fall and transported by ambulance to Speare Memorial Hospital in Plymouth, Mahar said.

This was the second serious accident in a week at a New Hampshire resort. On Tuesday morning, a 70-year-old woman and an employee of Gunstock Resort fell 30 feet from a viewing platform at the top of the Panorama lift. Both were seriously injured and transported by air to Dartmouth-Hitchcock Medical Center.

Mahar said the Loon zip line was closed temporarily but reopened Thursday afternoon about 3:45 p.m.

No information on the man's condition was available.
