Below are some photos from a trip to the Monte Rosa – Matterhorn region of the Alps in late September 2011. Our plan was to climb the main Dufourspitze peak of Monte Rosa. At 4,634 metres (15,203 ft)，Dufourspitze is the highest peak completely inside Switzerland. Our start was delayed three days by bad weather, with heavy snowfalls and we no longer had enough time for this trip. So instead we set out to climb Pollux, which involved around 5 km travel on a glacier at close to 4,000 m.

Lots of fresh snow slowed us up, and also made it more difficult to spot and cross the crevasses.
The snow gave way on me crossing a crevasse like this one. I yelled and Yannick ran forward so there was no slack in the rope and I did not go down further than my thighs.
It became clear after a couple of hours slow going over snow/covered crevasses that we did not have time to reach Pollux and back, so we headed instead for Breithorn.
