Monster is a Gerstlauer steel roller coaster at Adventureland in Altoona, Iowa.

At the bottom of the hill the riders reach a top speed of 65 miles per hour (105 km/h).

The car then goes into its only set of trim brakes, an overbanked turn and its final inversion, a corkscrew.

The ride features 2,500 feet (760 m) of track, five inversions and takes roughly two minutes to complete.

Monster features a nighttime LED display made up of 46 ground lights and 137 track-mounted fixtures provided by KCL Engineering.
