Themed trail Great Aletsch Glacier through the ages

Martin Nellen has been a mountain guide for 40 years. He long wanted to tell the story of the Great Aletsch Glacier. In cooperation with Dr. Hanspeter Holzhauser (geographer and glacier researcher), this has succeeded on this themed trail. Dr. Hanspeter Holzhauser created the concept and is the author of the texts, images, and graphics. The 4 information boards are based on his many years of research.

From Riederalp Mitte you hike eastward to the valley station of the Moosfluh glacier cable car. The cable car takes you to the starting point of the hike at the Moosfluh viewpoint. From there, follow the path eastward, via Biel down to the Chatzulechern. Four information boards along the path provide you with exciting information about the Great Aletsch Glacier: They inform you about the changes of the Great Aletsch Glacier since the last Ice Age (Würm glaciation) and show how the history of the ice giant can be reconstructed. 

• The first information board (Moosfluh, 2333 m above sea level) shows the extent of the Great Aletsch Glacier during the last Ice Age.
• The second board (Biel, 2280 m above sea level) documents the end of the Ice Age: It shows the moraine wall from 11,700 years ago.
• The third information board is located at the young moraine (2130 m above sea level). It shows the glacier status around 1860.
• The fourth board is 70 vertical meters above the glacier (2000 m above sea level). It explains how the history of the Great Aletsch Glacier can be reconstructed.
