The best tool needed for survival in the event you get lost when you travel is your skill of advanced planning. You must expect the unexpected and plan accordingly. Even if you are going out for just a few hours, pack enough essentials that you can stay hydrated (体内水分), fueled and prepared for any type of weather. Your essentials should include at least:

• More than enough food and water for the activity you plan.

• A compass that you know how to use. You may want a GPS device, but those sometimes do not receive a signal or the battery fails. Cell phones also likely will not work because of a lack of signal.

• Appropriate maps. Study the terrain (地形) and your planned route. Know where you are going and how you will return.

• Comfortable hiking boots, clothes that you can wear depending on the weather conditions and additional socks in case the ones you arc wearing get wet.

• A blanket, flashlight, matches kept in a water-resistant container, and other items that will help you survive overnight if necessary.

• Cheek with the local forest office for special warnings, such as fires in the area, bear sightings, flooding, trail or road closures, etc.

It’s also important that once you have planned your outing, tell someone. Give them exact details of where you are going, the trail you plan to follow, when you will return, the vehicle you are driving (and where you plan to park) and how many people will go with you—do not go alone.

If you do become lost, your most important tool is keeping a positive mental attitude.
