Karst - Wikipedia

Karst is a topography formed from the dissolution of soluble rocks such as limestone, dolomite, and gypsum is characterized by underground drainage systems with sinkholes and caves. It has also been documented for more weathering-resistant rocks, such as quartzite, given the right conditions. Subterranean drainage may limit surface water, with few to no rivers or lakes.
