It is created by the erosional forces of cascading water on the rocks at formation's base where the water impacts. The term may refer to the water occupying the depression, or the depression itself.

Shoot the Chute climb a 121-foot (36.8 m) lift-hill, round a curve, and descend a 115-foot (35 m) water chute at a 77.8-degree slope. Upon landing in the lagoon below, the boats create a 45-foot (13.7 m) high splash that drenches riders as well as spectators standing on an observation bridge overlooking the ride. The ride uses an adjustable electromagnetic braking system to control the volume of the splash. A similar ride, Hydro, was later constructed at Oakwood Theme Park in Wales, UK Holiday World & Splashin' Safari in Santa Claus, Indiana, built an even larger Shoot the Chute ride named "Pilgrim's Plunge."
