So anyone knows what is geologicaly happening here ? by Arsiesis Tags:switzerland 5 comments That’s a gypsum area, with lots of sinkholes/dolines. Check the aerial imagery to get a better impression, looks wild. (Edited, I originally wrote limestone, but that is not correct) Dolines in gypsum. Gypsum is an evaporitic rock/mineral that dissolves more rapidly than calcite/limestone. Geologically, on a slightly larger scale, a lot is going on (as in most of the Alps)! The Gypsum layer appears in black here: [https://data.geo.admin.ch/ch.swisstopo.geologie-geologischer_atlas_profile/profile/GA25_041_Plate_III.pdf](https://data.geo.admin.ch/ch.swisstopo.geologie-geologischer_atlas_profile/profile/GA25_041_Plate_III.pdf) It’s a very unique landscape. I ran through it once without having known about it beforehand…would love to go back and explore more. As others have mentioned: Gypsum that dissolves. But I wanted to add, that you have a very similar situation at the Col de la Croix between Villars and Les Diablerets Looks like a chunk of New Zeeland that eventually made it to the other side of the globe. This was the testing grounds during development of Swiss Zigerbombs. Comments are closed.
