BAR HARBOR, Maine — The National Park Service announced Sunday that it has ended its search for a missing hiker from Ellsworth.

“Based on an investigation of the circumstances and results of the search, the NPS and Maine Warden Service will resume operations as a recovery effort when conditions allow,” Acadia National Park spokesman John Kelly said Sunday in a news release.

Acadia National Park rangers, personnel from the Maine Warden Service, the Maine Forest Service and other dozens of volunteers began searching for Timothy Philpott after his car was found last Wednesday near the trailhead on Route 198 in Mount Desert.

The search team, however, did not locate Philpott or any sign of his presence during a systematic search of the area around Parkman or Sargent mountains on Thursday and Friday. The search also involved dog teams and aircraft.

The park service suspended the search on Saturday because of heavy snowfall that created unfavorable and unsafe conditions for the search team.

“We are grateful for the expertise and dedication of everyone on the search team, and especially thank the Maine Warden Service for its leadership in conducting the search,” acting Superintendent Mike Madell said.

“The park and community are very fortunate to have volunteers who are willing to donate their time and skills under such demanding conditions,” he said.
