National Park Service Rangers have recovered the bodies of a man and a woman from Massachusetts within Acadia National Park.

The as yet to be identified man, 28, and woman, 30, both from Rutland, MA, appear to have fallen 100 feet along ice covered cliffs from Dorr Mountain

An Acadia National Park press release tells us that their bodies were recovered today,  Saturday, March 20th, by National Park Service rangers working with volunteers from Mount Desert Island Search and Rescue (MDISAR) and a helicopter from the Maine Forest Service.  NPS rangers and Maine State Police are investigating, with the assistance of Bar Harbor Police Department.

The search overnight involved a U.S. Coast Guard helicopter from Cape Cod equipped with thermal imaging technology which searched for heat signatures on the north and east sides of Dorr and Cadillac Mountains without success.

The man and the woman arrived in the area this past Tuesday, and were last heard from Thursday when they discussed with family members via cell phone that they were interested in hiking Cadillac Mountain.  People became concerned Friday when they did not check out of their hotel as planned and hadn't returned to their vehicle.

A ground search including 15 volunteers and Park service staff began Saturday morning, and searchers on foot discovered them later Saturday morning.

Today these parks are located throughout the country in 25 states and the U.S. Virgin Islands. The land encompassing them was either purchased or donated, though much of it had been inhabited by native people for thousands of years before the founding of the United States. These areas are protected and revered as educational resources about the natural world, and as spaces for exploration.
