Not rocket science just axe/crampon technique that any geek can do.
Ok, I will agree that walking in crampons and carrying an ice is not rocket science, and many, many people safely do it each year without instruction or training. I was one of these people my first year out in the winter and thought like many people I see posting at this time of the year. Walking in good snow conditions is one matter, but when the snow changes abruptly or you hit ice under shallow snow and your crampons skid off, the feeling begins to change. Self arresting is easy when you are standing in a spot, slip a little and drop down to arrest and don't go anywhere, however a slip when you are not expecting it all can really change your perspective on not needing any training. People of all disciplines train skills so that when the s*** hits the fan, your instinct kicks in immediately. I can personally tell you that when you slip or stumble unexpectedly, especially on hard snow, seconds count and your training or lack thereof becomes a major factor.
If you are going to practice with a stove, why not practice self-arrest? Looking at pictures of self-arrest in FOTH is good, however you would be surprised how many people don't have the physical strength to sit up and plant their ice axe when falling head-first backwards or the danger of planting your ice axe too close to your body when sliding down a hill face first. Do you want to learn this when you are well-rested on a small slope with little hazard, or at 13k when you are fatigued and caught off-guard and sliding out of control?
My intention is not picking on Lacrosse's comments, many people will take this approach and get up and down safely, but do you want to be the one that doesn't? Even if you don't take a course in Snow Travel, please don't think it is always a straight-forward walk on snow with some spikes on your boots just because others have done it safely.
Have fun and stay safe out there.
