Gross Schiben west couloir left side 800m 4.3 E2

4 years ago, freshly arrived from Glion, I made my first couloir in Glarus, the Piz Sardona west couloir. Two month later Michal, Adelin and I made the first direct (red). Today I took a road already skied many (yellow) time but decide to move on left side to go thruh the last little couloir.

Starting with the first bus at 9h, I must make the long approach fast. This couloir was more a nice plan B but when I saw how dry, was my plan A I am happy to get so much choice.
