Today, we live in a world where GPS systems, digital maps, and other navigation apps are all available on our smartphones. [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 may help you navigate [5] to civilization, one of which is to follow the land.
When you find yourself [6] a trail, but not in a completely [7] area of land, 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.
Another [12]: Climb high and look for signs of human habitation. [13], even in dense forest, you should be able to [14] gaps in the tree line due to roads, train tracks, and other paths people carve [15] the woods. 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.
全文翻译
如今，我们生活在一个GPS系统、数字地图和其他导航应用都可以在智能手机上使用的世界。我们很少有人会不带手机就直接走进森林。但手机靠电池运行，电池耗电的速度可能比我们意识到的更快。如果你在没有手机或指南针的情况下迷路了，而且根本无法找到北方，有一些技巧或许能帮你找到回归文明社会的路，其中之一就是跟随地势。
当你发现自己偏离了小径，但并非身处完全荒无人烟的地区时，你需要回答两个问题：在这个特定区域，哪个方向是下坡？最近的水源在哪里？人类绝大多数居住在山谷里，依靠淡水供应。因此，如果你朝下坡走，并跟随着你找到的任何水源，你应该最终会看到人类的踪迹。
如果你以前探索过这个区域，留意熟悉的景象——你可能会惊讶于识别一块独特的岩石或一棵树竟能多快地让你恢复方向感。
另一个建议：爬高望远，寻找人类居住的迹象。例如，即使在茂密的森林中，你也应该能够发现因道路、火车轨道和其他人们在树林中开辟的路径而形成的树线缺口。朝着这些缺口走，就能找到出路。在夜晚，扫视地平线寻找人造光源，比如火光和路灯，然后朝着光污染的光芒走去。
最后，假设你是在人类经常出没的地区迷路了，寻找我们在环境中留下的痕迹。小径标记、轮胎痕迹和其他特征都能引导你回归文明。
