What is a shake hole?

A shake hole is a type of geological depression or sinkhole typically found in karst landscapes, formed by the collapse of a cave roof or the dissolution of underlying limestone. These features often appear as circular or oval-shaped holes and can vary in size. Shake holes can collect water, leading to the formation of temporary ponds or wetlands, and are often associated with unique ecosystems. They are significant in understanding subsurface water flow and the dynamics of karst environments.
