GRAND CANYON NATIONAL PARK, Ariz. -- Authorities say nine people have been hurt in a multi-vehicle crash at the Grand Canyon.
National Park Service officials say the crash occurred about 2 p.m. Thursday and involved a tour bus with a dozen people onboard, a minivan and a sedan.
Chief Ranger Bill Wright says one person was flown to Flagstaff Medical Center with serious injuries. Hospital spokeswoman Starla Collins says the hospital received one other person from the crash whose condition is unknown.
Seven others were transported via ambulance for medical treatment.
Wright says the sedan and tour bus appeared to have collided head-on, with one vehicle ricocheting into another. The cause of the crash on the road that leads to the East Rim of the canyon is under investigation.
Two parked vehicles also were damaged.
