Backcountry Tips Follow these simple and easy backcountry suggestions to minimize your chance of having to call 911 to be rescued. Always tell someone where you are going and when you will return. Have them call 911 if you don’t show up or check in on time. Never divide your hiking party. Always stay together! If you get lost or separated from your party, quit moving around and stay put. We’ll find you!!! Carry a plastic whistle. We might not hear your voice, but we will always hear that whistle. Carry a flash light or head lamp, whether you intend to be out at night or not. Carry and map of the area you are hiking and always know where you are at all times. Carry a compass and learn how to use it. Never wear cotton clothes. Cotton holds moisture and even on summer days can lead to hypothermia. Cotton Kills!!! In spring, summer and fall, always take rain gear. In winter always carry extra clothes. In any season carry plenty of water. When the water is half gone, it is time to turn around. Carrying some extra food, like a couple of energy bars never hurt anyone. Carry a first aid kit and know how to use it. Support Vail Mountain Rescue Donate All Rescues Are Free of Charge! CALL 911 FIRST so we can BE MOBILIZED.
