The 10+ Essentials The original "10 Essentials" list started appearing in hiking and climbing publications in the 1950s and 60s. With changing environmental issues and advances in technology, it's grown a bit, but it's still not too unwieldy. The 10-Plus Essentials 1. Map (in a watertight case) 2. Compass (plus an optional GPS receiver) 3. Extra clothing (men's, women's, kids') 4. Extra food and water 5. First-aid kit 6. Headlamp or flashlight (with extra batteries) 7. Matches (storm proof, or in a watertight container) 8. Fire starter 9. Knife (or multi-use camp tool) 10. Sunglasses 11. Sunscreen 12. Water filter (or other method of water treatment) 13. Whistle 14. Food storage device 1. Map: if you're hiking on an unmistakable trail or will be away from people, a map is essential. But not just any map: those undetailed handout maps you can pick up at the trail-head are fine for finding points of interest along the trail, but they're next to useless if you get lost. They don't have enough detail to help you figure out where you are and how to get to where you want to be. Carry a good topographic map that covers the area of your hike. 2. While GPS units are handy and convenient, they're no replacement for a compass. Suppose your batteries die, or you break your GPS in a fall? A good compass isn't very expensive. Of course you'll take the time to learn basic orienteering and route-finding skills before you hit the trail, right? A good place to start is http://www.compassdude.com/ 3. Extra clothing, because the weather can change unexpectedly, leaving you wet and cold. And it's not all that hard to lose your balance when crossing a stream and fall in. Besides, while it's a beautiful 80° right now, what if you're out all night, and the temperature drops into the 30s or 40s? 4. Extra food: you're not planning to be gone long, so why bother? Well, nobody plans to get lost or injured, but it still happens. Bring along some extra nutrition, even if it's just a freeze-dried meal or some energy bars. 5. First aid kit: because you never know. There are some great lightweight kits available, and they usually leave room for you to add some personal extras, such as prescription medications, etc. 6. Headlamp or flashlight with extra batteries: again, you didn't plan to be out all night, but here you are just the same. Besides helping you find your way, it can be used for signaling. 7. Matches (storm-proof or in a watertight container): Self-explanatory. And don't rely on convenience-store matchbooks--they're too flimsy and unreliable. 8. Fire starter: something to help you get a fire going quickly. You can buy commercial fire-starters in paste or block form, or you can bring some dry tinder in a Zip-Lock bag. 9. Knife or Multi-Tool: handy for gear repair, first aid, or starting a fire. Even a folding pocket knife works. While some people like the Swiss Army-type knives with scissors, screw drivers, etc., some folks consider them luxury items. But I've never once been in a situation where I said to myself, "Gee, I sure wish I hadn't brought this pliers/can opener/screw driver/ scissors/tweezers with me." 10. Sunglasses: protect your eyesight! 11. Sunscreen: The Mayo Clinic recommends SPF 15 or better. And bring lip balm, too! 12. Water filter/purifier: That mountain stream sure looks pure, doesn't it? Well, so did that spinach you bought last week. Remember that? The spinach that gave you that nasty e. coli infection? Without recommending any particular brand, I will say that I carry a Katadyn Hiker Pro--even when I'm carrying extra water bottles. 13. Whistle: Sure, you can always shout for help. And after 4 or 5 hours when you hear the rescuers calling your name, it's too bad—you've already shouted yourself hoarse and can't answer them. Besides, you can hear a whistle over longer distances. 14. Bear-resistant food container: these containers are like gravity--More than a good idea, it's the law! There are an increasing number of places where not using an approved bear-proof container can be your entry in the "Congratulations, you won a trip to federal court and a $5,000 fine" sweepstakes. Which is only a marginal improvement over the bear that just clawed its way into your tent to get that candy bar you left inside your pack.
