The Technique of Travel : Page 136
Locate your position. Take immediate bearings.
and record your bearings as you travel so that you can backtrack if you have to. The last man, with compass, should direct the party's route, taking care not to be misled in judging direction by the optical illusion brought about by swirling clouds.
Keep warm. There is little chance to warm up ifyou become cold. If there is climbing to do, put on climb ing skins before it becomes too cold. Chilled fingers are almost useless. In very cold weather keep a scarf or facemask over the nose and mouth to prevent freezing of the lungs, or draw the parka hood across the face and breathe the air that has been warmed by the body. Don't overexert.
