During the last glacial period, the Rhine Glacier reached a thickness of almost 1600 meters near Bendern.
At the coordinates you can find a few boulders (picture 1). These boulders are made of a stone only to be found in this part of the Eastern Swiss Alps. They are part of a typical geological formation of the area.
Nearby, there are glacial abrasion marks (picture 2).
In glacial abrasion, glaciers knock off and drag very hard boulders and gravels on their path to melting. The contact points between the entrapped rocks and the surrounding bedrock act like a giant piece of sandpaper, either scratching grooves in, or smoothing the abraded surface - as can be seen here.
To log this cache, take a picture of the location and your GPSr* (*optional) in front of one of the rocks, and answer the following questions:
- (1) What is the name of the glacial formation you can discover here? (10 letters)
- (2) Find the name of the "Knollenschicht" (6 letters). It is named after a mountain in Switzerland.
Both answers can be found at the cache location. And if you have some time to spare, take a short walk up to the chapel (there is a multi-cache to explore) and enjoy a scenic view of the Alps.
Now send a mail to
firstname.lastname@example.org - replace 10letters with the answer to question 1, and 6letters with the answer to question 2 - don't forget the dot in between.
If your answers are correct, you will receive an autoresponder message allowing you to log the cache.
