You need something that can help you protect yourself in the wild, as there will likely be numerous animals that are happy to eat you. Therefore, a weapon is a must and making one earlier in your trek is smart. One of the best ways to survive when lost out in places like this is to consider two types of weapons.
You want a blunt object that can be thrown. This means you can find a brand or stick that is sturdy and bigger on one side or you can add something to it by tying it on as a makeshift tomahawk. A spear is also a big addition, as you can make a fine tip by sharping it with things like a rock along with a knife if you have one.
