Frostbite is the freezing of body tissues because of prolonged exposure to cold. The most susceptible areas to frostbite are the feet, hands, ears, and face. Prevention is key for both hypothermia and frostbite. Remember a few simple rules: Eat high-energy foods and drink plenty of liquids. Stay rested. Wear the right clothing and bring layers. Don’t do something that will get you wet, and get out of the woods if you do get wet on a cold and windy day. Bring an extra set of clothes in case you get wet.
Avalanches
Understanding how avalanches occur and how to avoid them is too big a topic for this book, but a few words of warning can help you avoid a tragedy. Remember that you are most vulnerable to an avalanche when you are on moderately steep slopes (very steep slopes may not hold enough snow to avalanche), the lee side of mountains, or in gullies. Unstable snow conditions most often occur during or right after a storm; the bigger the storm, the bigger the risk. If you plan to do a lot of backcountry travel, take a Level One Avalanche Course, which will teach you how to determine avalanche risk, and how to work with beacons and probes to rescue those who have been caught in an avalanche.
