United States Army Training film TF31-2138 Public domain film from the National Archives, slightly cropped to remove uneven edges, with the aspect ratio corrected, and mild video noise reduction applied. The soundtrack was also processed with volume normalization, noise reduction, clipping reduction, and/or equalization (the resulting sound, though not perfect, is far less noisy than the original). http://en.wikipedia.org/wiki/Camping ..."Winter camping" refers to the experience of camping outside during the winter -- often when there is snow on the ground. Campers and outdoorspeople have adapted their forms of camping and survival to suit extremely cold nights and limited mobility or evacuation. Methods of survival when winter camping includes: building snow shelters such as quinzhees, igloos, or snow caves, dressing in "layers", staying dry, using low-temperature sleeping bags, and fueling the body with appropriate food... The equipment used in camping varies with the particular type of camping. For instance, in survival camping the equipment consists of small items which have the purpose of helping the camper in providing food, heat and safety. The equipment used in this type of camping must be lightweight and it is restricted to the mandatory items. Other types of camping such as winter camping involve having specially designed equipment in terms of tents or clothing which is strong enough to protect the camper's body from the wind and cold. Survival camping involves certain items that campers are recommended to have with them in case something goes wrong and they need to be rescued. A survival kit includes mandatory items which are small and must fit in one's pocket or which otherwise could be carried on one's person. This kit is useless in these circumstances if it is kept in the backpack. Such a kit should include a small metal container which can be used to heat water over a campfire, a small length of duct tape which can prove useful in many situations, and an emergency space blanket. These blankets are specially designed to occupy minimal space and are perfect for making emergency shelters, keeping the camper warm. Also because of the aluminum-like color this blanket is reflective which means it can be easily seen from an aircraft. Candle stubs are good in starting a fire as well as in warming an enclosed space. One or two band-aids are mandatory in this type of camping. Any camper, and not only the survival ones, need waterproof matches and a large safety pin or fish hook which can be used in fishing. Rubber gloves, antiseptic wipes, tinfoil, jackknife, or halazone tablets (which purify the water) are also to be included into a survival kit. Although these seem too many items to be carried on one person, they are in fact small, lightweight and definitely useful. Winter camping can be dangerous without respecting the basic rules when it comes to this particular activity. Firstly, the cold is protected against with clothing of three types of layers as follows: a liner layer against the camper's skin (longjohns), an insulation layer (fleece), and a water- and wind-proof outer shell. Although cotton is one of the best quality fabrics there is, it is not recommended to be worn on winter camping because if it gets wet it dries out very slowly and the wearer could freeze. Rather than cotton, winter campers should wear wool or synthetic materials. The boots must be waterproof and the head must be protected against the cold. Although it seems a good choice, campers are advised not to wear too many pairs of socks as they might restrict blood flow to the feet, resulting in cold feet. Gaiters should also be worn to avoid snow and rain wetting the boots. Secondly, one should include carbohydrates into their diet to keep their body warm as well as to provide energy. Hydration is very important so winter campers should drink plenty of water to keep themselves well hydrated, noting that water stores must be kept from freezing. Thirdly, the tent must be carefully chosen to shelter it from the wind...
