Description

The Trümmelbachfälle is is advertised as underground waterfalls. We categorized it as a gorge with waterfalls, but nevertheless most of a visit takes place underground. The small river Trümmelbach is fed by the glaciers of the famous Eiger (3,970m asl), Mönch (4,099m asl) and Jungfrau (4,158m asl). This are some of the most impressive mountains of Switzerland and the Alps, to a little above 4,000m asl, one slightly below. This catchment area has a size of 24 square kilometers. The high mountains are a major tourist destination, developed for mass tourism by several cable cars and a famous rack railway.

During snow melt in spring, and sometimes after heavy rains, the Trümmelpach may have a production of 20,000 liters of water per second. The river transports about 20,000 tons of rocks every years by the power of the water, and so it created a narrow gorge over the millennia. This gorge is so narrow, the visitor has the impression to be undergound. Ten of the waterfalls have been developed by stairs, tunnels, and galleries. An underground funicular brings up to 500 visitor per hour up to the waterfalls,

The gorge developed during the last 15,000 years, when the end of the last cold period of the Ice Age came. The glacier in the deep Lauterbrunnental, a typical U-shaped valley which was formed by a glacier, started to melt. Water from the surrounding mountains had to descent deeper and deeper into the valley. Forming a waterfall over the rim, the Trümmelbach started to millcut and saw into the hard rocks. The rocks were very hard, but the water was powerfull, and the gravel it transported gave it a lot of abrasive power. The gorge cut in fast and thus narrow, the ravine is steep and the water has a very high energy.

The underground elevator is a funicular, which is a sort of cable car on rails. Two cabins are connected by a steel rope which runs over a wheel on top, thus the wheight of both cabins is in an equilibrium. The motor has to lift the wheight of the passengers, accelerate and deccelerate the cabins and to overcome friction. This one is a little different: there is only one cabin, the counterpart is just a wheight, which is about the wheight of the cabin plus 15 persons. The first elevator was built in 1913, since then it was renovated twice. The current cabin from 1983 has a glass ceiling, enough space for 40 passengers and lifts them 100m on a distance of 105m.

The whole path through the gorge is today 600m long, 400m of galleries, five tunnels, and 30 meters of bridges. The deep and dark gorge is lighted by 16 floodlights and 32 spots.
