From experienced mountaineers and the Book Freedom of the Hills. These items are the Ten Essentials that will help you to be prepared for the unexpected, aid in survival and can be life savers in an emergency.
A map and compass prevents one from getting lost in the field. Take along maps that cover the relevant area in sufficient detail and dimension (topography, trails, roads, campsites, towns, etc.) and learn how to use a map and compass together especially when the place you are traveling lacks signs, markings or guides. A GPS is always helpful but should not be taken instead of a map and compass. The accuracy of GPS is dependent on Terrain, foliage, barometric pressure and user knowledge, all of which have an effect on how accurate the GPS readings are.
Sometimes things happen and nightfall comes before we are at our destination. Flashlights and headlamps protect against physical injury when traveling in the dark and are helpful when searching in the dark or signaling if there is an emergency. Always be sure to bring extra batteries and bulbs.
Extra food and water can in case of an emergency prevent hypothermia and give clarity of mind when dealing with an emergency situation. They also keep you healthy and prevent illness from setting in. Never eat without water, as the body needs water to metabolize food.
Extra clothes will protect you from the elements and hypothermia. A multiple layering technique of clothing will keep you warmer than just on single heavy layer, as warm air is trapped between layers of clothing forming an insulating layer. Layering your clothing also prevents over heating but still will protect you from bugs, sun, wind and foliage. They can be used for many things in an emergency situation including bandages.
Sunglasses protect your eye sight and help prevent snow blindness in snowing environments.
A first aid kit usually contains items to treat cuts, abrasions, blisters, punctures and burns plus allow you a place to carry prescription medications. Be sure to take a first aid kit that is fitting to the area you are planning you trip.
A knife is very useful in the backcountry but a multi-tool such as a Leatherman or Swiss Army Knife is a very versatile choice.
Waterproof matches and fire starter such as a magnesium stick will keep you warm preventing hypothermia, food consumption to cook on as well as a signaling device.
A water treatment device such as a water filter or chemical tablets makes water potable and safe for drinking. All water needs to be treated for bacteria and viruses in order to ensure safety and prevent sickness. Water filters work well but are more expensive than alternative chemical treatments of Iodine or chlorine. If neither of these methods is available to you, bring water to a rapid boil for one minute before consuming.
