Calvin Charles Zimdars, 56, was last seen at his home in Glen, Montana, on November 29, 2017. He disappeared from the 1000 block of Sugarloaf Mountain Road, leaving his vehicle, prescription eyeglasses and other personal items behind. His car was inoperable, and family and authorities considered it possible he left on foot. He had turned his horse out to graze before he vanished, a detail officials noted as suggesting he might not have planned to return soon.

An avid outdoorsman familiar with the local hills and mountains, Zimdars is described as white, 5 feet 5 inches to 5 feet 7 inches tall, 140 to 170 pounds, with blue eyes, black hair with some gray, and a dark brown and black beard. Distinctive scars include marks on the back and sides of his neck, small scars on his chin, and a raised thick scar on the right side of his abdomen. A nine-day search of the area around his home found no trace, and the active search was suspended pending new information. His family and community have been deeply affected and his case remains unsolved.

If anyone knew Calvin’s habits, recent movements, or saw him on or after November 29, 2017, please share what information is available.
