SWITZERLAND - UNESCO WELTERBE TEKTONIKARENA SARDONA

Return to Lisbon i had in my mail box a lot of postcards. 

Here we can see 3 postcards from Unesco site of Welterbe Tecktonikartena Sardona.

The area in which the thrust is found was declared a geotope, a geologic UNESCO world heritage site, under the name "Swiss Tectonic Arena Sardona." The area of this "tectonic arena" encompasses 32,850 hectares of mainly mountainous landscape in 19 communities between the Surselva, Linthtal and Walensee. 

In the arena are a number of peaks higher than 3000 meters, such as Surenstock (its Romansh name is Piz Sardona, from which the name comes), Ringelspitzand Pizol.

The region was declared world heritage in July 2008, because "the area displays an exceptional example of mountain building through continental collision and features excellent geological sections throughtectonic thrust.
