A 69-year-old man from Buckhannon has gone missing while on a hunting trip in northern Utah, according to the Summit County Sheriff’s Office.

Carl L. Crumrine was last seen Monday morning at about 5:30 a.m. as he left his campsite and was walking toward Lyman Lake, according to a press release. Lyman Lake is located near the Wyoming border, deep in the Uinta-Wasatch-Cache National Forest, a vast stretch of land that encompasses nearly 2.1 million acres.

Crumrine was in Utah as part of a hunting trip, according to the release. His group went looking for him when he did not return and then contacted authorities later Monday.

Local media in Utah reports that a search-and-rescue operation is underway involving searchers on ground, horseback and by helicopter.

The weather is currently in the 60s by day and 30s at night, but that is expected to drop as the weekend approaches, with nighttime temperatures falling into the teens.

Crumrine is believed to be wearing a camo shirt, coat, pants and a hunter orange vest, as well as Muck boots, a camo hat and camo backpack. He is also thought to have taken his hunting rifle with him. Crumrine is 5-10 and weighs 240 pounds, with gray hair and blue eyes.

Anyone with information is asked to contact the Summit County Sheriff’s Office at 435-615-3600 or 435-615-3526.
