Crystal clear water, lit by a sunbeam, flows fast among boulders covered with a thick layer of moss. Above, a thin layer of dried leaves brought by the stream, is deposited over the moss acting as a filter. In downstream, the transparent water is flowing, continuously releasing the air bubbles previously incorporated on the downfall.
