Skiing in the Winter Wilderness: Page 16
All in all, this design had antifreeze advantages. It also had a built-in rest inhibitor: when it was full, you could turn over only by mutual consent.
Its minor disadvantages, I still insist, are far outweighed by its virtues, among them its lightness in weight —less than a pound per man. Another, its streamlining and low silhouette, important in high winds. Its worst feature was that it could be snowed in because it was so low. Its best feature was by all odds its cooking space, a vented floorless area in the sloping front. Here your snow mine, which is to say your water supply, is right at hand. You scoop up snow as needed for melting on the stove. If someone tips the stove over—and someone always will—you don't have to rely upon the sleeping bags' blotting up the soup. The snow in the open floor space soaks it up instead, and if you happen to scoop up a little frozen soup when melting snow for your coffee, who's the poorer?
