Pearl Shoals Waterfalls - Jiuzhaigou
Rushing water. Same waterfall, different location, feet were almost in the water with the 24mm glass on the camera.
An interesting feature of this waterfall is that it is growing outwards rather than eroding backwards as most waterfalls do. The reason for this is that calcium carbonate is combining with roots, leaves and branches to produce a matrix of cemented plant-stone, which then continues to grow once established. Additionally, since the water flowing over the shoals is shallow and filtered, lacking abrasive sand and gravel material, it has little erosive power that might otherwise cause the waterfall to erode back up the valley.
