A karst landscape is a unique geological formation characterized by features such as caves, sinkholes, and underground rivers. This type of landscape forms primarily in regions with soluble rocks, like limestone, which dissolve over time due to water erosion. The result is a dramatic terrain with steep cliffs, deep valleys, and various natural openings. Karst landscapes are often rich in biodiversity and can support unique ecosystems. They are found in many parts of the world, including regions like the Guilin in China and the Carlsbad Caverns in New Mexico. These areas are not only important for their natural beauty but also for their geological and ecological significance.
