What is a solution pit?

A solution pit is a geological feature formed by the dissolution of soluble rocks, such as limestone or gypsum, often resulting in a depression or hole in the ground. This process occurs through the action of water, which can dissolve minerals over time, leading to the formation of underground cavities. As these cavities grow and eventually collapse, they create a surface depression known as a solution pit. Such features are commonly found in karst landscapes and can impact local hydrology and ecosystems.
