a. DO NOT travel in— (1) Blizzards. (2) Bitterly cold winds. (3) Poor visibility. b. Obstacles to winter travel follow: (1) Reduced daylight hours (BE AWARE). (2) Deep soft snow (if movement is necessary, make snowshoes [Figure 2-10]). Travel is easier in early morning or late afternoon near dusk when snow is frozen or crusted. (3) Avalanche prone areas to avoid: (a) Slopes 30-45 degrees or greater. (b) Trees without uphill branches (identifies prior avalanches). (c) Heavy snow loading on ridge tops. (4) If caught in an avalanche, do the following: (a) Backstroke to decrease burial depth. (b) Move hand around face to create air pocket as moving snow slows.
