Lake Winnepesaukah has the oldest ride of what type, which finishes with a climactic splashdown?
Old Mill (ride) An old mill is a type of amusement park ride with unaccompanied boats floated on guideways through dark tunnels. These themed dark rides originated in the late 19th century and are known by a variety of names, including tunnel of love and river cave. While generally considered a gentle ride, a variation that ends with a climactic splashdown, similar to the modern-day log flume, is known as a mill chute.
'Opaeka'a Falls ʻ Ōpaekaʻ a Falls is a waterfall located on the ʻŌpaekaʻa Stream in Wailua River State Park on the eastern side of the Hawaiian island of Kauai. It is a 151–foot waterfall that flows over basalt from volcanic eruptions millions of years ago. Below the ridge down into the ravine through which the water falls can be seen the vertical dikes of basalt that cut through the horizontal Koloa lava flows. The name "ʻ Ōpaekaʻ a" means rolling shrimp, "ʻ opae" being Hawaiian for "shrimp," and "kaʻ a" for "rolling". The name dates back to days when the native freshwater shrimp "Atyoida bisulcata" were plentiful in the stream and were seen rolling and tumbling down the falls and into the churning waters at the fall's base.
