Waterfall in a rock cave in Scotland

Smoo Cave (Scotland) is divided into 3 parts and the most attractive part is the 3rd cave with beautiful waterfall hidden among the green and gray limestone floors.

Cave waterfalls are a testament to the continuous erosion in the Early Stone Age to create extraordinary natural architectures. Often the water flow will flow continuously on the same stone surface for hundreds of years until it corrodes the penetration layer and allows the water to flow through to form a waterfall.

Another theory is that the stone surface has a gap and the stream just flows. In addition, corrosion at Smoo Cave is a combination of seawater flow and freshwater continental crevices crept between limestone floors. Although very popular in games or virtual worlds, the waterfall in the cave is very rare in real life.
