Karst

Karst changes the way water moves through a landscape. Instead of following only visible surface channels, some water enters fractures, enlarges passages and emerges elsewhere. This is why an apparently dry surface can be connected to an important underground water system.

For the visitor, the useful habit is to look for relationships. A cave entrance, a disappearing stream and a spring may belong to the same broad kind of process, even when the actual connection requires scientific investigation. Tall limestone landforms above ground are only one expression of karst.

Caves are fragile environments with their own hazards. Understanding how they form does not confer permission or competence to explore an unregulated passage. Use established visitor routes and leave mineral formations untouched.
