The thing to note about the 1st shelter (with the mylar blankets) is that this will keep you warm for a few hours, untils condensation from your own body humidity starts to accumulate and then you'll start being cold & damp. That's a good way to keep warm for a bit, you HAVE to get off it regularly, and that's not a good way to spend the night.

Great video. A survival shelter needs to be made quickly. Most videos of “survival shelters” describe methods that take so long to build, you would freeze to death before you finish them.

Do you make a good point. It’s true that you must consider conserving calories when building shelter.

Aren't those blankets insulators? As in wouldn't you be insulating from each other when back to back rather than sharing heat? Genuine question.

He still transfers through the backs of those mylar blankets. You should try it and see for yourself. It’s not like a sheet of metal and you don’t feel any heat through it. The blankets are very minimal and desperate intervention in a desperate situation but they help.

Top. Sehr schön vorgestellt. Genau so geht es 👌👍

Thanks KZread, 3 years late but at least we got here.. haha ! see if this video now blows up

Beautiful snow fall 🇵🇰

I thought tree wells were something to avoid because of how dangerous they are. I can’t believe it would be a good idea to try to make a shelter in one. The snow at the base of the tree might have been impacted by the water vapor given off by the base of the tree. This could cause it to have a slushy consistency making it very easy for someone to fall deep under the snow and suffocate. I’m not an expert at all but just a quick search online makes me think that going near tree wells is a bad idea.

Thanks for your comment. Back country skiing and snowboarding enthusiasts are very familiar with the dangers of tree wells. I personally have been part of search and rescue teams looking for lost and deceased subjects that have perished because of tree Wells. There is however a distinct difference between someone skiing with speed and velocity colliding with a tree or falling in and suffocating because they cannot release themselves from their bindings. What I am Suggesting is that if you’re traveling through the back country and are desperate to make shelter you can blend in with your environment conserving calories and energy by improvising a tree well into a shelter. If you have ever done this you would understand the advantages. You already have cover overhead. There is less digging because the tree well. You can manipulate and reinforce the area. There are of course disadvantages such as low visibility for search and rescue. I have a winter Survival Course coming up the end of this month in collaboration with California survival school. It will be three days and two nights. Come train with us. Find more information on my website Earthwalkerllc.com

Doesn’t the tree well act as a cold sink? I’ve wondered about sleeping in depressions.

Sleeping in a tree well that you modify with a sleeping shelf can be a life-saving strategy. Imagine the contrast of sleeping with no protection at all in the snow. With the advent of a tree overhead providing shelter and a space underneath that you modify, such an alternative is exceptional. I have slept quite comfortably in such spaces.

@@earthwalker9211 I understand that the tree well has “built-in” walls. I was thinking of mounding snow to make a windbreak/berm vs dropping in a hole. But I do anything to get out of the wind and worry about “cold sink” later.

It is wise to accommodate to “cold sink” and it is wise to conserve calories and water with the output of labor. Tree wells are not always the best option but they can be altered accommodating for “cold sink” with less energy out put compared to building a snow shelter from scratch.

Those blankets are useless. Get the 2.5 thick SOL ones.

I agree that the thicker space blankets are more durable and more reflective but if you are desperate , the small space blankets are far better than having planned for no emergency provisions. When I build survival kits, I think of multiples (having layers of protection by having multiple essential items) these small blankets are one way to supplement and support other shelter systems in place for thermoregulation. You can stuff them within your clothing, put them under you on the ground, wrap yourself in it. I have been in freezing water and then wrapped myself in just one of these cheap space blankets and believe me, you can feel the heat being reflected back to you.

In cold conditions it is supposed that you keep the silverized side of the space blanket in the inside in a way to reflect your heat back to you. The way you show in the video is correct for warm climates when you want to reflect heat from the environment away in a way to avoid heatstroke. Is not responsible trying to teach others the wrong way to do things!

The mylar blanket was first designed by NASA astronauts and is used to this day in many constructive way from thermoregulating homes to survival gear. The blanket you speak of is a more advanced design with two sides. One side is plasticized and the other side has mylar. The mylar used in this video was a very extreme minimalistic example of the common small Mylar survival blanket. It does in fact have reflective heat value and also prevents convective heat loss. If you have ever tried this, actually placing a Survival blanket around your shoulders you’ll feel this within seconds. What I was demonstrating was in a situation where there is a white out and you have not prepared a suitable structure, as a last resort to prevent possible death , you can dig yourself a snow trench and sit back to back for conductive heat transfer. With the advent of a mylar blanket you may live. Mountaineers and winter survival specialist know this. In an extreme situation this would be much better than the fetal position at the base of a tree with nothing at all. I can assure you of my responsible role in the community instructing search and rescue teams, local sheriff and general public. All the best. Stay safe-

I thought the eventuality you were using only silverized blankets. They are not common. As you said experts know what to do. The video should be addressed to "non experts" and which probably possess the "normal" double side blankets and need to learn the way to use it correctly. At least specify in the comments is important. Merry Cristmas and Happy New Year.
