We have blizzard lines strung out every where so you can hold on or pull yourself along when visibility is almost zero. If you let go or there is no rope you have to use your memory to find your way around. Large deep snow drifts make moving around very difficult and strong gusts can easily blow you off the rope or off your feet for that matter. It's extremely difficult to breath and fine snow finds its way under your clothing and into all areas. I even had a glove blown off my hand. Often you have to stop and find some temporary shelter to regain your composure as the whole experience is extremely tiring and claustrophobic. Try doing it at night? You get the message !!
