Mammoth is a water coaster at Holiday World & Splashin' Safari in Santa Claus, Indiana, United States.

[2] The track on Mammoth is made out of numerous pieces of molded, red, yellow, and blue fiberglass supported by concrete pillars.

The track features a conveyor belt lift hill as well as six linear induction motors that propel the boats back uphill, including the longest LIM on a water coaster.

[2] The technology on HydroMagnetic Rockets utilizes linear induction motors (LIMs) to propel boats uphill.

An alternating magnetic field beneath the slide surface interacts with a steel plate mounted on the underside of each boat to push them uphill smoothly and quickly.

At this point the boat makes a right turn before entering the ride's initial 32 feet (9.8 m) drop at a 45° angle.

At the conclusion of the drop it lands in a splash pool of water, floating in a current with mild rapids for several yards before making a left turn to line up with the end-of-the-ride conveyor belt.

Due to these factors, Mammoth closes when there is lightning or high wind in Holiday World's immediate area.

All riders must abide by Splashin' Safari's dress code, which includes wearing modest swimwear or clothing, in order to ride.
