I found a great article on winter survival that points out 5 common sense skills to survive in the winter if you ever find yourself stranded or lost during this season.
Your first priority in winter is to build a shelter to get out of the elements, especially the cold and the wind, which can cause hypothermia and frostbite. If you’re in the open and everyone in your group is mobile, you need to get below treeline. Studies of winter accident reports have shown that people who get below treeline survive far more often than those that don’t. The trees will protect you from the wind and provide fuel for making a fire.
If you’re pinned down by the weather or a member of your party is injured and can’t be moved, digging a snow cave, a snow pit, or a snow trench will get you out of the wind. Snow is an excellent insulator, so make your shelter as enclosed as possible, while still providing adequate air flow. But don’t underestimate the effort required, especially if you don’t have an avalanche shovel.
This article also discusses an overlooked necessity but is very essential for survival – staying hydrated.
It’s important to stay hydrated in winter, especially in a survival situation, as a defense against hypothermia and frostbite. If you’re out of water and not near a freely running water source, you will have to melt snow for drinking water. If you don’t have a stove or cook pot to melt snow with, you can try putting snow in a water bottle and placing it in your coat to melt it. Don’t do this however until you have a fire going and can stay warm. It can take rescuers a lot time to get to you, possibly days, and having water and fire will keep you alive even if you’ve run out of food.
