|It had rained heavily all morning but after lunch we decided we would drive out into the Lauterbrunnen valley. All along the high cliff valley there were cascades of water. After driving to the end of the road we stopped and visited the Trümmelbachfälle . These falls were spectacular. The majority of the falls are inside the mountain. Up to 20,000l of water per second corkscrews through ravines and potholes shaped by the swirling water. The 10 falls drain from 24 sq. km of Alpine glaciers and snow deposits. The noise and extent of water was amazing.
