Switzerland--Remodeled

Karst landscape refers to the dissolution of one or more layers of soluble bedrock. Switzerland contains 7,900 square kilometers of karst landscape, which makes up 19% of Switzerland’s surface. This karst area is where the majority of the 7,500 currently known Swiss caves are found.

The above picture was taken inside the Hölloch cave system, which is located in canton Schwyz, Switzerland. When translated into English, Hölloch means Hell’s Hole. This is a karst cave and is nearly 200km long.


The picture below was taken in Glattalp, which is located in central Switzerland. Glattalp is one of the few karst landscapes located in Switzerland.

Switzerland has a diverse glacial landscape. One erosional form that Switzerland is famous for is the Matterhorn. The Matterhorn is a Horns landform that was formed from erosion on all of its sides. Erosion did not happen evenly, as seen below.

Switzerland is home to many parabola, or "U" shaped valleys. They form as glacial ice carves through  "V" shaped valleys.

Reichenbach, located near Interlaken. It is in the Kander Valley. 


Glaciers are a common landform in Switzerland. A famous glacier is the Aletsch glacier, which measures at 45 square miles of ice. The glacial ice always moves down, as seen below.

The Aletsch Glacier is the largest and longest glacier in the Alps. 
It is located in the Bernese Oberland. 


 Rivers carry all sizes of clasts in their bedload from the weathering Alps. Sediments such as glacial flour from the summer melting of the Aletsch glacier will travel in a suspended load and be deposited in the Swiss plateau when it reaches base level.

The Lutschine River, located in the Bernese Oberland, carries snowmelt that will supply the Swiss people with drinking water, visible here are the large clasts in its bedload.
