Patrick Terrence Whalen, 33, a registered nurse and self-described survivalist, was last seen November 2, 2000, in Glacier National Park, Montana. Originally from Cleveland, Ohio, he was living in Portland, Oregon, and had been traveling through Glacier Park, Blackfeet tribal lands, and Columbia Falls for several weeks while planning to become a naturopathic doctor.

Whalen’s vehicle was found at the Lake McDonald Lodge Restaurant near U.S. Highway 89 and State Highway 49. On May 27, 2001, a park ranger located his abandoned campsite near Cut Bank Creek at the Atlantic Creek Backcountry Campground; the site appeared untouched since the previous fall and contained personal belongings but no clues to his whereabouts. Reports note he had been struggling with mental health issues, including paranoia and obsessive behavior, before he vanished.

Whalen remains missing and is considered lost or injured in the park. If anyone had contact with him in Glacier National Park or saw his vehicle or campsite in 2000, please share what is known.
