How do plunge pools form at the base of waterfalls?
Quick Answer
Plunge pools form when falling water and rock fragments erode the rock directly below a waterfall. The pool deepens as the waterfall retreats upstream.
The Full Story
At the base of a waterfall, the force of falling water hits the bedrock with great energy. Rock fragments carried by the flow act like tools, drilling and scouring a hollow known as a plunge pool. As the pool deepens, the cliff behind the waterfall can become undercut and collapse. This process helps the waterfall slowly move upstream over long periods.
