Plunge pool softer or fractured rock has been eroded back to a knickpoint, water continues to bombard its base. Because this rock is often less resistant than overlying strata, the water from the higher elevation continues eroding downward until an equilibrium is achieved. A somewhat similar bowl-shaped feature developed by flowing water, as opposed to falling water, is known as a scour hole. These occur both naturally and as a result of bridge building. Plunge pool A plunge pool (or plunge basin or waterfall lake) is a deep depression in a stream bed at the base of a waterfall or shut-in. It
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."
