The shellear fish can scale a 50-foot waterfall using specialized fins and a unique climbing technique involving breaks during its ascent.
In ice climbing, you want to try to have a solid base with your footing and to get the ice axes over the tops of each other to have the most leverage. We worked on these skills from the comfort of top roping, which entails having a fixed anchor you can rappel down from. This gives the feeling like you are in a climbing gym and greatly reduces the risks.
