OREM — A 34-year-old Bountiful woman was lifted out of American Fork Canyon Friday by helicopter after she was stabbed in the stomach by a tree branch.

The woman had been a passenger in a two-person all-terrain vehicle when she and the driver hit a dead tree in the road, said Utah County sheriff's deputy Collin Gordon. A 2-inch diameter branch went over the ATV's hood and into the passenger cabin, impaling her in the lower right abdomen.

There was only a small wind deflector, which wouldn't have stopped the branch anyway, Gordon said.

Other people in the area had a satellite phone and were able to call 911 just after 2 p.m.

"It's quite a long ways in, really rough and rocky to get an ambulance in; it's a very remote area," Gordon said.

The branch was removed at the scene, and the emergency crews were dealing with the bleeding.

When the first call came in, she was unconscious and having problems breathing, Gordon said. However, when officers got on the scene, she had regained consciousness and was talking.

The woman, whose name was not released, was taken to the hospital in critical condition, Gordon said. She was conscious and talking.
