WALKING IN THE HILLS 1.When ascending a steep slope zig-zagging is better than straight up. 2.Take care descending convex slopes you cant see whats ahead! 3.Contour around hills, rather going up and down all the time. 4.Early start and early to bed. 5.Wild country requires physical fitness. 6.Maintain your pace, shorten steps when going up hill. Do not keep stopping and starting 7. Wet grass and rocks are slippery. care in wet conditions.
NAISMITHS RULE This should guide you when working out timings when walking. On expedition with a full rucsac allow 4Km per hour and 10 minutes for every 100m climbed. ( one minute for each contour). The rule does not take into consideration the wind, terrain, or rests. So 4km maybe optimistic!!!
DRINKING WATER On expedition in mountainous country You will have to use stream or lake water. 1. Never use streams below the highest habitation(300m), 2. Only use fast flowing streams going over rock. 3. Check upstream for dead animals in the water. There is a risk of using such water but you can reduce the risks by: 1, Boil for 15 minutes. 2. Use a commercial filter 3. Use purifying tablets – follow the instructions! 4. Add few drops of iodine.
EXPEDITIONS IN WILD COUNTRY Distress Signals. Accepted signal is six blasts on a whistle, six flashes with a torch, shouts or waves of something bright. Wait one minute and repeat. Acknowledgement is 3 blasts or flashes etc.
MOUNTAIN RESCUE Rescue teams are voluntary and unpaid. RAF helicopters also help in rescues. Follow the following safety precautions if you have a team member who needs emergency aid. 1.Use the phone numbers in the order you are given on the red emergency card. 2. Be prepared to give your location and a six-figure grid reference and the condition of the casualty. 3. When help arrives the rescue team will decide whether a helicopter is required. FLARES – not used much but RED means emergency help required!
THE WIND CHILL FACTOR Loss of heat from your body can be increased even with a slight breeze. The higher you go the lower the temperature! EXAMPLE: If the temperature is 8 degrees and the wind speed is 15mph, the true air temperature is 2 degrees. As you gain height the air temperature drops. A warm day in the valley will mean winter like conditions on the tops, this does not include the wind chill factor.
LIGHTNING Violent thunderstorms can Be frightening in the hills. Keep of summits and ridges. Shelter behind rocks, in caves, or hollows. Sit out in the open on spare clothes or rucsac. Tuck knees under chin and clasp your legs. Put metal objects away from you.
