People always ask what you cover a Dubree hut with, and my answer is always the same, “whatever is available. ” I’ve used everything from an old piece of tin I found to pine bows and even sod; if you layer it, you would be amazed at how waterproof they are. Here are a few examples of different survival shelter coverings.
You can use pine bows.
You can use grass.
You can use bark.
Make sure you lay it like shingles, working from the bottom up, so the water will run off.
OR you can use a combination of more than one.
Ultimately, it doesn’t matter what you use as long as you can cover it and keep it warm and dry.
