A 19-year-old who teaches wilderness survival at a Colorado camp fought off a black bear on Sunday after waking up to the animal biting his head. The camp instructor, identified only as Dylan, told The Denver Channel he needed nine staples in his head after the attack. The teen said he woke up around 4 a.m. to a “crunching sound” as the bear tried to pull him out of his sleeping bag. He and other campers punched and swatted at the bear until it ran away. “The crunching noise, I guess, was the teeth scraping against the skull as it dug in,” he told a local news station. Colorado Parks and Wildlife spokeswoman Jennifer Churchill said the incident happened at Glacier View Ranch, 48 miles northwest of Denver. Churchill said traps and scent dogs would be used to try to find the bear, and any bears found would likely be euthanized.
