An 87-year-old Whitefish man who went missing in the Frozen Lake area last weekend was found alive Tuesday afternoon in Canada.

According to a press release from the Lincoln County Sheriff’s Office, Clifford Persons was picking mushrooms with a friend in an area Saturday about 11 1/2 miles east of Eureka. Persons’ son said his father was with a friend, but hadn’t returned to the vehicle.

Authorities said he was found Tuesday across the border and was being evaluated by medical personnel. No other information was immediately made available.

Deputies from the Lincoln County Sheriff's Office and members of Eureka-based Can-Am Search and Rescue assisted in the search, along with Two Bear Air Rescue, based in the Flathead Valley.

Ground crews and K-9s from Libby-based David Thompson Search and Rescue also assisted in the search, along with Flathead County Search and Rescue.

Montana Department of Natural Resources and U.S. Forest Service fire crews as well as U.S. Border Patrol also assisted in the effort.
