What is Karst?

Karst is a unique landscape characterized by soluble rocks such as limestone, dolomite, and gypsum that are susceptible to erosion, forming breathtaking caves, sinkholes, and underground river systems.

The word “karst” originated from Slovenia.

The term “karst” comes from the name of the limestone plateau in Slovenia called “Kras.”

Karst covers approximately 12% of the Earth’s land surface.

Karst landscapes can be found all around the world, spanning continents from Asia to Europe, and North America to Australia.

The Great Barrier Reef in Australia is a karst formation.

This natural wonder is one of the most famous examples of a karst formation, consisting of thousands of coral reefs and islands.

Karst landscapes are crucial water resources.

Due to the unique geological features of karst, it acts as a natural filtration system, providing freshwater resources for millions of people around the world.

The world’s deepest underwater cave is located in the Karst region of Czech Republic.

The Hranice Abyss holds the record for being the deepest flooded cave, reaching a depth of 404 meters (1,325 feet).

Karst formations are home to diverse ecosystems.

From rare cave-dwelling species to unique vegetation, karst landscapes support a wide range of flora and fauna.

The Karst Plateau in Slovenia is a UNESCO World Heritage Site.
