I regularly see online that on expeditions snow anchors are strapped to the side of the backpacks. This is typically an item like the upper on following pic:
I never saw this in the Alps by myself. But I also saw it in this video where he shows his stuff for alpine multi day trips. I learned to build a deadman (snow anchor) with my ice axe. For more technical routes I have 2 axes and it's said that you could even use nearly anything to build a reliable anchor (poles, backpack, gloves and even a lighter).
- So what is the point in carrying this additional item?
- What are differences in using this snow anchor compared to using my ice axe?
- And what are the differences in the items seen on the pic?
- How does the actual activity/tour makes a difference what to choose?
