A man was detained after about three hours of negotiations with Billings police atop the Billings Rimrocks near North 27th Street.
The man was attempting to descend through a boulder-filled area when he was detained.
Several officers approached the man throughout the incident, but he kept his distance from officers. According to a press release from the Billings Police Department, the man appeared to be hallucinating.
He was taken to a hospital for treatment for hypothermia and frostbite.
