For sailing, I wish it was warmer. For climbing, I wish it was colder. Just no satisfaction....
- The hands are leashed to ice axes, which are sharp and designed to hook into the ice very strongly. Generally, a single sharp blow in the right spot (where the ice will not shatter) is all that is needed, rather like trying to set a roofing nail with one strike. Well placed, they can hold 700 pounds each... or nothing at all when placed poorly.
- The boots are armed with crampons, with sharpened points about 1-inch long. They are either lightly kicked or firmly placed where they can bite. The trick is to place them and then relax, without cutting your lifeline, the rope.
- If the rope is above the climber, it is a top rope, like the local climbing wall. Good if the ice is melting and less than secure. Falling becomes casual.
- If the rope is below, it is lead climbing. I have placed screws that can hold more than 2,000 pounds... if I have chosen the right place and the ice is good. I will fall some distance, perhaps 15 feet, until the rope catches. If the ice screw fails, I would fall past the next one; in this case, since the next screw is quite far below, I would hit the deck, about 40 feet down. It's best not to fall even the shortest distance on ice, since the crampons often catch, causing broken ankles.
