Today we live in a world where GPS systems, digital maps, and other navigation apps are available on our smart phones. 1 of us just walk straight into the woods without a phone. But phones 2 on batteries, and batteries can die faster than we realize. 3 you get lost without a phone or a compass, and you 4 can’t find north, a few tricks to help you navigate 5 to civilization, one of which is to follow the land... When you find yourself well 6 a trail, but not in a completely 7 area, you have to answer two questions: Which 8 is downhill, in this particular area？ And where is the nearest water source？ Humans overwhelmingly live in valleys, and on supplies of fresh water. 9 , if you head downhill, and follow any H2O you find, you should 10 see signs of people. If you’ve explored the area before, keep an eye out for familiar sights—you may be 11 how quickly identifying a distinctive rock or tree can restore your bearings.

Head toward these 16 to find a way out. At night, scan the horizon for 17 light sources, such as fires and streetlights, then walk toward the glow of light pollution. 18 , assuming you’re lost in an area humans tend to frequent, look for the 19 we leave on the landscape. Trail blazes, tire tracks, and other features can 20 you to civilization. 1.
