Descending 180 feet below the surface.

Tiefenhohle Laichingen is one of the deepest caves in Germany. It was discovered in 1892 after a pile of sand collected on the surface used for cleaning mysteriously disappeared. Thinking someone stole the sand the sand miner sat up all night waiting to catch the thief but later realized the sand was falling into a crack in the ground.

Blautopf (German for Blue Pot) is a spring in the city of Blaubeuren and a drain for the Blau cave system. The waters blue color is a result of physical properties of the nanoscale limestone densely distributed in the water. The particles are so small that the so called Rayleigh scattering of light takes place scattering the blue color in the visible light. Similar effect is observed in the Blue Lagoon in Reykjavik, Iceland.
