A teenager's first day on the job at Yellowstone National Park ended in tragedy when she lost her footing on the rim of a canyon and plunged 400 feet to her death, reports Fox News. The 18-year-old reported for work Thursday at a private concessions company and later went hiking with three others at the park's Grand Canyon. She apparently walked off the trail, and the loose rock "quickly gave way underneath her," according to a park statement.
