ALFALFA COUNTY, Oklahoma - An 18-year-old from Carmen, Oklahoma, was injured after he crashed his four-wheeler in Alfalfa County Friday afternoon.

It happened at 5:30 p.m. on Carmen Park Road at Carmen Park. Troopers say a 2006 Suzuki Quadracer ATV driven by Zachary Bowden was southbound on Carmen Park Road when it ran off the roadway to the right for an unknown reason.

According to the Oklahoma Highway Patrol, the ATV traveled about 67 feet before hitting large chunks of concrete. It continued to travel south and hit a tree. The vehicle then flipped half time, and landed about ten feet down at the bottom of a dam.

Bowden was pinned under the ATV for about five minutes before being freed. He was transported to St. Mary's Hospital in Enid and was admitted in stable condition with head, trunk internal and external, and arm injuries.

Troopers listed Bowden's condition at the time of the crash as "apparently normal." The cause of the collision is listed as "unsafe speed- exceeding legal limit."
