There's very little Duct tape can't do. It can help with blisters, assist with marking your trail, make items waterproof, and it can even help you start a fire. If you bring enough (and are very talented) you could even build your entire shelter with duct tape and sticks. No word on how long that might take, but hey, good luck!
