Stream crossing.—Ordinarily the ski tourer can cross the smaller high-mountain streams on a snow bridge, taking care that the bridge is substantial, that his weight is evenly and gradually applied, and that only one skier at a time try to cross. Failing to find a snow bridge, the skier should look for a log crossing, take off his skis, and proceed cautiously. As a last resort, it may be necessary to rig a raft of some sort. The buoyancy of air mattresses should not be overlooked. Also dead, dry logs may be cut with the lightweight saw blade (see p. 78). Particularly toward the end of the day, when there is little chance to dry out and get warm easily, the skier should not take chances of falling into a stream. The danger of freezing afterward is serious. |
