Always carry a detailed map of the area you will be visiting. If alpine scrambling or otherwise navigating cross-country consider the 7.5 minute USGS maps--they reveal considerable detail. For traveling on trails, the 15 minute series Green Trails is a good choice, among others. The point is to carry a map appropriate for the area you will be in and the activity you will be undertaking--and know how to use it !
Carry a compass, at all times, in the backcountry--and know how to use it ! Some features to look for:
The following compasses are lightweight and would be the minimum you would want to carry. They probably would suffice as an emergency gear item while backpacking entirely on trails.
For serious backcountry travel where map and compass will be used for navigation, the following compasses are recommended:
3. Flashlight / Headlamp:
Flashlights and/or Headlamps are important even on day trips. You never know when you might need to spend the night or make that last mile or so after sunset. Here's some features to look for:
It's a good idea to carry a small lightweight hand-held light in addition to a headlamp. In the handheld light use a regular bulb which requires less battery juice than the bright-beam bulbs. Use this light for simple around the camp chores, to conserve batteries. In the headlamp, use a halogen (or other bright-beam bulb) and use this light when you are path finding or otherwise require a bright beam.

4. Extra Food:
Whenever you go out, even for a day trip, bring extra food in case you are delayed by emergencies, foul weather, or just get lost. The mountaineers suggest a one-day supply. At the very least, bring one good meal more than what you need. The food should require little or no cooking. If your extra food will require cooking, make sure you also carry extra fuel for your stove.
5. Extra Clothing:
In addition to the basic layers you would normally take on an outing, bring extra clothing which would get you through an unplanned bivouac through the worst conditions you might come up against.
In addition to the extra clothes, carry an emergency shelter such as a waterproofed tube tent or mylar Space Bag (or blanket). The Space Bag only weighs about 2.5 ounces but will completely encase you and keep you warm and dry.
Your eyes can experience damage from the intensity of mountain skies, ultraviolet rays, and light reflecting off of snow. As elevation increases so does the intensity of ultraviolet rays. Adequate eye protection is a must ! Bolle' makes a lightweight pair of glasses with a virtually indestructible polycarbonate lens. They are optically correct and have emerald green lens for true color. They are rated 100 % UV protection. Cost is about US $40.00.
For traveling on snow, get a pair of glacier glasses with side shields which reduce reflective light reaching the eyes. Good, quality glacier glasses typically cost in the $50 to $150 range. Nikon makes some nice ones with polycarbonate lens. They are very lightweight, cost is about $110.
There are many other brands of sunglasses and glacier glasses which are less expensive and provide adequate protection. Shop around, but be careful. Try to stay with reputable brand names. Your eyes will know damage, long before you feel discomfort.
7. First-Aid Kit:
Carry first-aid supplies for minor injuries. In particular, carry plenty of adhesive band-aids and sterilized bandages, because they can't be easily improvised in the woods. What to carry ? A good book to reference is "Mountaineering First Aid" 3rd edition, by Lentz, Macdonald, and Carline, published by The Mountaineers.
This booklet was used as a text when I took the Mountaineers' MOFA (Mountaineering Oriented First Aid) course. I use it now to refresh my memory. It is easy reading, small ( 5 1/4 x 8 1/2 inches ), brief ( 95 pages ) and inexpensive ( $8.95 ). It identifies what items to carry, as well as what to do in emergency situations.
Once you are familiar with the supplies you need, you can purchase a kit or make your own. If you purchase one, you'll most likely need to add to it ( items like CPR mask, rubber gloves, etc. ) since most commercially prepared kits are inadequate.
Also, If you spend any time in the backcountry, it would be a good idea to enroll in a mountaineering first aid course.
(NOTE: Within the "Weight-Saving Tips" page at this site, are many improvisions which can be used in emergency situations--"in lieu of packing the kitchen sink").
8. Pocket Knife:
Your basic tool kit. A good example of a single piece of gear which has multiple uses. For example, a Wenger "Master" Swiss Army Knife has a locking blade; "slip-joint" pliars/wire crimper/wire cutters; springless self-sharpening scissors; wood saw; nail file/cleaner; corkscrew; awl/reamer; can opener; cap lifter; tweezers; and toothpick--all at a weight of about 6 ounces. Swiss-Army knives are available with more and less features.
At a minimum, knives are useful for first aid, food preparation, cutting moleskin strips, cutting rope and making repairs. However, scrutinize your needs before you go out and buy a honker like the Victorinox Swiss Champ which has many tools you probably don't need and weighs 1/2 pound ! If you don't actually use a feature, then you probably don't need to be carrying it around.
9. Waterproof Matches:
Carry matches which have been waterproofed or wind and waterproofed, or else carry extra strike-anywhere matches--along with something to strike them on-- in a waterproof container. Keep these matches separate from your regular match or butane lighter supply. Keep them available for emergency situations.
There are many commercially prepared waterproof/windproof matches available on the market, e.g., "Hurricane" and "Cyclone" brands of wind & waterproof matches and Coghlan's waterproof safety matches.
Fire starters are useful for quickly starting a fire, especially in emergency situations. They are also useful for igniting wet wood. There are several commercial fire starters available: magnesium blocks w/striking flint; chemically-treated fire sticks, etc.
In addition, numerous home-made fire starters work just fine: plumber's candles (wax); compressed balls of dryer lint mixed with or covered with melted parafin; small strips of waxed cardboard (from old produce boxes); small flammable containers--individual egg-carton cups filled with mixtures of wood shavings, wax, & lint; etc.
11. Water / Filter / Bottles:
Carry plenty of fresh water. If you are familiar with the area in which you are traveling, and can be sure that water sources are available, carry enough water to get you there.
If you aren't bringing your water from home or a public source, treat the water you draw from the backcountry, regardless of the source. These days, everything is suspect.
Use water filter, purifier, chemical tablets, or boiling to treat the water before consuming. ------------------------- For transporting inside your pack, use lightweight water bottles, such as Nalgene 16 oz and 32 oz lexan polycarbonate or high-density polyethylene wide-mouth bottles. Some folks use other containers such as old plastic pop bottles. That's okay too. Be careful they don't crack and/or leak, though.
For emergencies: when you're lost, someone else is lost, or you're hurt and need help, etc.
Caution: Metal whistles, with a pea, can be a problem in the mountains. Your "pea" can freeze up, and what happens when you put your lips on frozen metal ?
A better choice would be a pealess plastic whistle like the Fox 40. It is ultra-light and very shrill. Cost about $6.00. REI sells em.
13. Insect clothing or repellents:
I don't know about you, but summer really "bugs" me. Three ways to deal with the biting flies, mosquitoes, knats, etc. are to (1) let them eat you (2) use repellents or (3) wear clothing. Since the first option doesn't cut it, there are numerous commercial repellants on the market. Most of them are DEET based. REI Jungle Juice works okay but the stuff gets everything oily. There are many good creams but they need to be reapplied more frequently. There are extended duration DEET products which do not soak into the skin as fast and provide up to 12 hours of protection--such as 3M Ultrathon (now only available as "Hourguard 12" thru Amway).
I've found, recently, that the bugs seem to be getting immune to the juice, so I've been wearing an ultra-lightweight bug-netting jacket and pants. This has been successful, except when I bend over and expose my lower back where the jacket rides up. If you go this way, make sure the garments are very baggy. Many bugs have long stingers that easily penetrate tight fitting netting.
14. Sunburn preventatives:
Remember, the higher the elevation, the greater the burning-capacity of the sun. Although each person's pigmentation is different, thus, each of us has a different capacity for withstanding the sun's onslaught, the message is the same--the penalty for underestimating your need for protection is severe, even deadly !
In sunny conditions, wear light-colored clothing and cover exposed skin, at least, with SPF rated sunscreen appropriate for you, at least 15. Wear coverings over the neck and ears. OR (Outdoor Research) and other manufacturers make baseball-style caps with skirts which cover the neck and ears. Carry an SPF-rated lip-balm, as well, and reapply frequently.
