What is a waterfall plunge pool?
Quick Answer
A plunge pool is the deep basin at the base of a waterfall, carved by the force of falling water and swirling rocks. It can become much deeper than the surrounding riverbed.
The Full Story
As water drops over a waterfall, its impact on the base creates turbulence and powerful erosion. Rocks carried in the water help grind out a hollow basin called a plunge pool. Over long periods, this erosion can undercut the waterfall and cause it to retreat upstream. Plunge pools are common at many large waterfalls, including those in glacial and volcanic landscapes.
