Be very well observed. In the corridor and later in the continuation of the cave, calcite plates piled up on each other on the sides. Long ago on the surface of thermal waters thin lime films separated out, which grew, be¬came thicker, later sank onto the floor of the cave and piled up there. Later, with the decrease of the water level, peas tones deposited on the lime films. During the develop ment of the cave these got to surface.
