A teen staffer at a camp in Colorado woke up Sunday to find a bear biting his head and trying to drag him away.
The 19-year-old reportedly woke up to a "crunching sound" with his head inside a bear's mouth. Colorado Parks and Wildlife spokeswoman Jennifer Churchill said the bear was trying to pull the teen, later identified only as Dylan, out of his sleeping bag as he slept outside at Glacier View Ranch.
The teen and other staffers, who were sleeping nearby, were eventually able to fight he bear off.
Dylan told ABC affiliate KMGH-TV that the bear dragged him ten to 12 feet before he was able to escape.
"The crunching noise, I guess, was the teeth scraping against the skull as it dug in," Dylan explained to KMGH-TV.
After the attack, Dylan received treatment at a local hospital and was released. Dan Hansen, director for the Glacier View Ranch, told KMGH-TV that the summer camp program will continue through July 16. He added that staffers are trained for contact with wildlife including moose, wild cats and bears.
Typically black bears aren't aggressive, but in recent weeks several people in the West have been attacked.
A woman and her dogs were attacked Tuesday in the Idaho Panhandle National Forests. And last month, black bears killed two people in Alaska.
Black bears have been known to defend their young and to paw and bite tents with food inside. Wildlife officials, however, didn't find any food that would have attracted the bear to the Colorado campsite. Wildlife officers have since set up bear traps in the area and plan to search for the bear with scent dogs on Monday.
