Quick Answer
Look for fallen tree branches, branches with a suitable diameter for roof support, sturdy leaves or grasses, and large rocks or boulders to use as building materials in the wilderness.
Branches and Logs
When searching for branches and logs, focus on areas with fallen trees, dead branches, or trees that have been weakened by wind or disease. Look for straight, sturdy branches with a diameter of at least 2-3 inches (5-7.5 cm) for support beams, and smaller branches for roofing. Measure the length of the branches you find by comparing them to your body or use a stick to mark a length of about 10 feet (3 meters). Use a sharp rock or knife to trim branches to the desired length.
Leaves and Grasses
Leaves and grasses can be used as a water-resistant roofing material or to create a thatched roof. Look for areas with a high concentration of leaves, such as near water sources or under deciduous trees. Measure the thickness of the leaves and grasses by comparing them to your thumb; if they are around 1/4 inch (6 mm) thick or less, they are suitable for use as roofing material. Use a stick to collect the leaves and grasses, and spread them evenly across the roof.
Rocks and Boulders
Large rocks and boulders can be used as building blocks for a rock shelter or as a foundation for a log cabin. Look for areas with a high concentration of rocks, such as near streams or in rocky outcroppings. Measure the size of the rocks by comparing them to your body; if they are around 2-3 times larger than your head, they are suitable for use as building blocks. Use a stick to lever the rocks into place, and create a stable foundation for your shelter.
