ACADIA NATIONAL PARK – A New Jersey woman was lowered to safety down the face of the Beehive mountain on Monday after she tumbled down the rocky terrain and injured her shoulder and back, park Ranger James Grover said Tuesday.

Two dozen park rescue personnel answered the 4:15 p.m. call, Grover said, and got Leslie Bobella, 49, of Murray Hill, N.J., to an ambulance at the trail head more than three hours later.

A sophisticated system of ropes and other technical equipment was used to lower Bobella over the edge of the Beehive, a mountain that juts up over Sand Beach and features one of the most popular trails in the park.

Bobella was hiking the trail with her husband and their three young sons, Grover said. Her husband, a doctor, assessed her injuries and provided aid until the rescuers could reach her.

Grover said the family had hiked about halfway up the 520-foot-high rock when Bobella lost her footing and tumbled down 20 feet, landing in a ledge area. The rope system used by the rescuers was able to support Bobella and two medical technicians, Grover said.

Rangers lowered the trio as far down as they could, then belayed Bobella safely to the ground. They hiked 20 minutes on the Beehive trail to get her to the ambulance, Grover said.

A spokesman for Mount Desert Island Hospital said Bobella was discharged Tuesday. Grover said he believed she had broken a shoulder in the fall.

Bobella complained of chest and back pain after she fell, so the rangers had to assume she could have suffered a spinal injury, Grover said.

Given the terrain, lowering Bobella over the face of the mountain was the quickest and safest rescue route, Grover said.

“For safety’s sake, it had to be handled like this,” he said.

The rescue team, led by Rangers David Smith and Richard Rechholtz, included six experts from the Mount Desert Island Search and Rescue Association.
