A Fallen tree branch appears to have caused the Ninja roller coaster to derail Monday at Magic Mountain, stranding riders for nearly three hours before they were rescued.
Fire Inspector Fred Flores told The Times that the incident occurred when the coaster struck a branch that was lying on the track, derailing the first car.
The Ninja will remain closed while inspectors survey the track and surrounding area.
