Humans have a few intuitions about how temperature, heat, and liquids work. These intuitions lead us astray for the specific case of a bladder full of urine. "Keeping Warm" / "Cooling down" The f...
You can't. The theory required you to get samples and send them to a lab, which wouldn't exactly be practical in the field anyway. METAL ABSORPTION BY EQUISETUM (HORSETAIL) A19 GOLD ...
The main reason that I found is for cutting a cornice, sometimes referred to as the bombs of the backcountry. Extending the handle allows one to cut it without being too close, and as for why o...
As to why you're still cold with those specs: it happens to me as well, and I think the specs are for the 'average' person meaning not only average amount of body fat but also average temperature r...
There are many factors to consider when purchasing skis, but for the most part, unless you're an avid skier and recognize the advantages of having one pair of skis over another then it's probably n...
We use both. It is not difficult to light a fire with a ferrocerium rod especially if you have pine trees around as we do. A bit of sap from one of them on your shavings, cotton balls, spanish moss...
A point others haven't stressed enough is that the sleeping bag specs I have encountered are way off, in my experience. My experience is that the sleeping bag should be as warm as possible, under a...
I find that an inflatable mat allows for a great deal of cold from the ground to reach you/warmth from you to be drawn out. I sleep on an Exped downmat, which although is an inflatable mat, is fil...
The math is trigonometry but I think you would need to get a feel. It is not like you could run the math on the fly anyway. The ratio of sin above and the sin below is 1.33. More angle is more ...
Another reason for extending a snow saw handle is for preparing a snow stability test, for avalanche awareness. There are various such tests and most initially require digging a trench then isolati...
The easy technique is to simply hold the spear in your hand with the tip under the water and stab the fish. Once your spear enters the water, refraction has identical effects on your view of the s...
One could use many natural things as a projectile, but I will limit my answer to two items and the lethal possibilities would depend on how close you are to the victim. This is such an expansive qu...
I'd try a higher r-value pad or add a pad. There is a fair amount of variation in what people say you should use (in fact checking this post, it was r1.5 to r5). If your 2.8 isn't cutting it for ...
Moving vertically +-2m is a lot. An awful lot. It shouldn't be more than a few cms. This sounds like there's something else going on. Good buoyancy requires lots of practice to master. The bes...
I use lighted nocks on my arrows because it helps me judge the quality of the arrow strike on an animal. When the LED on the arrow tip flies across your field of vision, it leaves a trace in your ...
I ended up buying two different pairs of removable sole coverings with a sandpaper-like material on them (appropriately called Sandy and Sandy Plus, made by a company called Springyard in Sweden): ...
Avoiding Pump: Warm up, warm up, warm up. To avoid serious arm pump you need to do at least 15 minutes of EASY climbing. That's 15 minutes of you doing what you feel is exceptionally easy, even if...
Probably, but it likely wouldn't keep you as warm underneath unless you wrapped it all the way around, in which case you have almost duplicated a sleeping bag. Depending on the temperature it mig...
This is a supplement to @Ken Graham's excellent in-depth answer. It's an expansion on a link he referenced in his second picture, which seems to perfectly fit the criteria you're seeking. The org...
I would simply go by the loft. More specifically the minimum loft. If some baffles have blown out the bag is not as effective. I don't have source but I read lumberjacks that use the bag year ro...
It seems that that there is at least one company that has wheelchair accessibility for railbike riding. It is in Belgium as can be seen here. Biking on rails: it is not an activity we do in th...
The name change is going ahead, at least for now The Ahwahnee Hotel and other Yosemite National Park landmarks soon will be renamed amid a legal dispute between the government and the facilitie...
Disclaimer: I don't use whippets and have never even hold one in my own hands. From the build of a whippet and a question about whippets on AAI (provided by Ben Crowell) it has a very narrow use c...
How about leaving the PADI fold and moving on to other styles of diving, for example technical diving: where you can learn to do much longer dives with decompression (an hour at 30 metres?); wher...
This typically indicates you have movement in your shoes, perhaps your insoles are worn and squashed and need replacing. The balls of your feet sliding on the bottom of your boot will eventually bu...
