Four people received minor injuries as Ninja derailed after hitting a tree that had fallen against the track.
Nearly two dozen riders were safely rescued after being stranded 20 feet off the ground. The impact caused the first car to derail, injuring the passengers riding in that car. All of the passengers were said to be alert and talking with park personnel during the evacuation process.
Two of the injured were taken to a local hospital as a precautionary measure. One of the riders reportedly complained of neck pain, the second, a knee injury.
The ride will remain closed until a thorough inspection of the area is complete.
