BAR HARBOR, Maine — Rangers came to the aid of a woman who fell and injured an ankle in Acadia National Park on Wednesday.

Rangers and other emergency responders carried her out on a litter along a rough trail for over a mile, reported Ed Pontbriand, supervisory ranger.

The woman, 57, was hiking with her husband on the Cadillac Cliffs Trail when she slipped on wet rocks, fell and injured her ankle, said Pontbriand. Her ankle was fractured or dislocated, he said Thursday. Per the national park’s policy on injured visitors, the woman’s name was not released.

The couple, from South Burlington, Vermont, had to hike some distance in order to be able to get cellphone service and call 911 about 1 p.m.

Responders came to the scene, hiked in, gave the woman medical care, and carried her out to the trailhead and parking area.

Removing the woman was somewhat difficult, indicated Pontbriand. “It was a really, really rough trail,” he said. It took about an hour to carry her out, he said, and the group arrived at the trailhead and a waiting ambulance at about 4 p.m. She was transported to Mount Desert Island Hospital for treatment.

Besides rangers, other responders included Mount Desert Island Search and Rescue, Bar Harbor Fire Department paramedics and a hospital physician.

Pontbriand issued a reminder that cellphone service is not available in all areas of the park. Hikers should wear proper shoes and be prepared by having a backpack with some food, water and a map, he suggested.
