When it’s peeling, you can collect tree bark from trees like tulip poplar, basswood, and hickory that have a flexible bark. Select a young tree with thin bark. The tree should be less than 6 inches in diameter for best results. Also, make your selection in a thicket if possible, to open it up for the benefit of the other trees. If you have a hatchet or saw, cut the tree down and drag it out of the thicket. In a primitive survival scenario, you can use a sharp rock that weighs about a pound as a bark chopper to remove the bark without cutting the tree down. If you’ve cut the tree down, cut around the tree about 2 feet up from your felling cut. Then score a line parallel to the trunk which connects the two cuts. Mimic those cuts while the tree still stands, if you are using a stone chopper. When you’ve finished your cuts, carefully peel the bark off, and then you’re ready to make a container.
