The National Park Service says it is continuing to look for a man believed to be missing in Acadia National Park.

Timothy Philpott, 50, was last seen Tuesday in Ellsworth. Park employees spotted his car in the Parkman Mountain parking area on Wednesday and believe it had been parked there the day before. They searched around the parking lot and tried calling Philpott but did not spot him or make contact with him.

On Thursday, the National Park Service searched hiking trails around Parkman and Sargent mountains. They were assisted by Mount Desert Island Search and Rescue volunteers and the Maine Warden Service, which provided an airplane to search from the air. The search was expanded Friday, with more than 25 volunteers and several search dog teams, along with the Maine Warden Service and Maine Forest Service providing airplane and helicopter searches.

The National Park Service said Friday it will now assess the status of the search and weather conditions to determine the next steps.
