Fig. 4. Snow cave for one man. One-man snow cave.—The simplest bivouac for a lone skier provided with a sleeping bag and a waterproof outer cover is the one-man cave. In the shelter of an overhanging conifer or beside a rock or log, or best of all, under a bent-over sapling, a cave can be kicked into unconsolidated snow with the boots, or dug out of packed snow with a cup or cooking pot in a few minutes. The cave should be just large enough to squeeze into after the lining of fir boughs or the air mattress has been inserted. If a slope is not available a pit can be dug 31/2 feet deep and the cave dug as a drift from the pit. For greater warmth the top of the pit should be covered with boughs and snow blocks. |
