Sledge, Pulk?
People trying solo traversals and winter ascents of Denali have tried
horizontally carrying ladders or long strong poles (and back packs). The advantage on temperate/continental glaciers unlike ice sheets is that you have an idea of flow direction and some sense (but not always) how crevasses run (rememeber: not always like bends/turns). I have also read (source?) that some people use two long poles that are put together to form a cross and attach this to their hips, so you don't have to worry about the directions of the crevasses (as long as the crevasses are not bigger than the cross). However I have a hard time imaging how help yourself once such a cross has stopped you from falling (remember you are still soloing). Bernd |

However I have a hard time imaging how help yourself once such a cross has stopped you from falling (remember you are still soloing). One presumes one doesn't always punch all the way through (figure that most of the time you are toast [Simpson being a rare exception]). You'd have many of the same problems breaking thru lakes except snow bridges are weaker than lake ice, and you don't get any buoyant advantages with air below your feet. The problem is figuring out how long to make the poles. Longer - heavier, so it's just another part of the knapsack problem. This is why Messner doesn't like soloing across crevasse fields. But he does it (w/o any of this). -- |

Sledge, Pulk?
to unshod walking boots except for very wide crevasses as in large enough to swallow a sno-cat (think Mawson's Will and his ponies breaking through snow bridges). Then the ski gives you a false sense of security I thought Mawson used dogs and got vitamin-A poisioning from their livers. Wasn't it Scott who tried ponies? -- These are my opinions, not necessarily my employer's. I hate spam. |

Scott used Siberian Ponies, Shackleton also used ponies. Every one used dogs. Scott tried tractors. I can't remember all the details of Mawson w/o going back to Will (those polar books blend together) but I recall one of the accounts watching some disappear into the abyss. Scott's ponies had snow shoes, those are still at Cape Evans, and I remember seeing horse feed at Cape Royds outside Shackleton's hut. All the English had problems with dogs and skiing. Scott only had 4 pairs of skis for the five of them on his ill fated push. This little fact tends to get overlooked by armchair explorers. -- |
