World renowned naturalist and tracker Tom Brown Tom Brown, developed the concept of the debris hut. Well actually, he had nothing to do with it, it was the squirrels idea. You see Tom and his friend spent a few cold nights shivering in the forest before “Grandfather” suggested they go ask the squirrels. Soon Tom learned the secrets to their homes and consequentially spent many warm nights with only that which nature provided. All this is another story… check it out in Tom Brown’s Field Guide to Wilderness Survival, or several of his other books also share the story.
The simple concept is to build a frame just large enough to lie down in, then heap on debris from the forest floor until you have a thick mound of leaves and such. The principle is the same as down, the thick layers trap air, which once your body heat warms up, acts as insulation and keeps you warm. (If you’ve ever seen a squirrels nest up in a tree, you know the big ball of leaves…. Well, there you go!)
If you pile on enough debris, and then fill the inside of your hut, smash that down, and repeat several times so there is a thick layer of insulation under you, followed by any creative way to have a door to keep in the heat, then it is said a human will stay warm in very cold temperatures, even if it is wet. I however am part reptile, and therefore a bit sluggish in the cold, so I opted to keep a sleeping bag in my hat for added warmth. Plus, with 12 debris huts in the area, the debris was having to be gathered in mass quantity.
Here’s what I learned:
- Keep the peak of your roof trim, without long sticks rising above it. They trap the debris on top, and leave a shallow spot underneath.
- If I was to stay in one without a sleeping bag in cold weather, then the advice of having the debris in a thick enough mound that I could stick my arm in, up to my shoulder and not touch the structural sticks….. well, that would be a must. Otherwise it just isn’t enough insulation.
- However, it rained freezing rain, and I stayed quite dry! The key I’m told is a rounded mound to shed the water.
- A lightweight tarp is a key element to take along in the woods. It is much easier to pile on leaves and drag it to your hut, then carry it all by the armful. Additionally, it is the quickest, easiest door. (Unless you’re going all natural.)
- Find a good spot with plenty of the right size sticks, and plenty of leaf litter.
- Start early! Building a debris hut not only takes quite a bit of time, it consumes quite a bit of energy. I would not want to be starting late in the day on this in a survival situation.
- Sleeping close to the earth feels good
- If there will be more than 1 hut, build them very close together, it saves time filling the in between with debris.
- Sleeping in a debris hut will bring you closer to mother earth and all her life. It will teach you something about you own back yard, which in today’s world is becoming more and more foreign.
