DENVER - Riders were stuck aboard a rollercoaster at Elitch Gardens for about 20 minutes Wednesday afternoon.
Zach Street tweeted photos of the ride, showing the train stuck on the crest of a hill above the theme park's midway.
The Sidewinder rollercoaster came to a halt in the middle of the ride, said spokeswoman Jessie Falk. It had to be manually brought back into the station before the passengers could be unloaded.
So far, Falk said, the cause of the malfunction is unknown.
