The initial investigation indicates the ATV driver was travelling at an excessive speed as he drove across an uneven portion of the dirt road making it difficult to control the vehicle. It appeared the vehicle left the roadway at this point, entered a shallow ditch and when the driver attempted to re-enter the roadway, the vehicle rolled several times before coming to rest.(Photo courtesy of YCSO)
EMS personnel arrived, treated the injured man before he was flown to Flagstaff Medical Center.
As of Sunday, he was listed in critical condition with a broken skull and bleeding on his brain.
