Search teams in Colorado are looking for a Minnesota hunter who went missing in the mountains.
The Routt County Search and Rescue told 9News in Denver that 41-year-old Richard Harkins went bow hunting on Monday and separated from his group in Steamboat Lake State Park, near Steamboat Springs.
He sent a text message that day, but hasn't been heard from since, with rescue teams conducting searches on foot and from the air. A U.S. Air Force helicopter with infrared equipment has been brought in to assist.
Steamboat Today reports Harkins is from Duluth. The newspaper spoke with his sister, Kristin Raver, who said he "grew up in the woods" and has good survival skills.
Given the time he has been missing, concern has grown considerably.
"I think by now he would have got out on a trail," Raver told the newspaper.
He had a cellphone with him, reports note, but authorities have so far been unable to track it. He is believed to be in the area of Sand Mountain and Meaden Peak, part of Colorado's Elkhead Mountains.
The fear is he's been injured and is stuck somewhere in the park, with search and rescue member Jim Linville saying it's difficult to spot people where he is thought to have gone missing because it's an area of heavy timber.
The Associated Press reports search dogs have been brought in to help, and riders on horseback will also be assisting.
