Check for signs of frostbite and pay attention to cold feet. Protected skin, as well as exposed skin, are all susceptible to freezing and toes are the most vulnerable. The first sign of frostbite is white patches on the skin surface. If the skin does not return to its normal color after applying gentle pressure, you should seek medical attention as soon as possible. If you are backcountry skiing in hilly terrain, climbing skins help you ascend hills with less effort.
Skins are slightly narrower than the width of a ski.
They attach to a ski by straps or an adhesive backing. As you gain altitude, food takes longer to cook. Plan meals that do not require a lot of boiling. Pack a colorful bandana in your pack. In the rare event you need to signal rescue workers, you can attach the bandana to your ski pole and use it as a flag.
