Having been dumb enough to try this (albeit with a 500m tunnel), I will mention a few drawbacks: Trains going downhill make very little noise, and tunnel rails are often specially damped, so you ...
Expanding on cutting cornices, here's a video clip of ski guide Theo Meiners using an extended snow saw to drop a cornice. Note that most everything happening in that video is intentional (if dange...
Per Western Mountaineering, American manufacturers of high quality down sleeping bags, Down also is known to have the greatest longevity, and it will outlast any other insulation by 3 to 5 tim...
The one shortcoming I find reading through many of the other answers is that they seem to skip over a major source of pollutants in backcountry streams: human waste. While you might not be downstre...
Lice are passed on by one of two manners. Either by direct contact or indirect contact with someone who is infected with lice. The chances of coming in contact with lice in the wilderness is excee...
A spit is not just any bolt. Spit means almost exclusively (especially among cavers, who care more about the what they are clipping into) the hand-drilled bolts now sold as Cheville autoforeuse by ...
I own both a 3 season tent and 4 season. I car camp in warm weather all the time with my 4 season tent because it is bigger. Once you unzip the door you get a lot of ventilation.
To make a hide, you need to steam, smoke, and degrease it. I doubt any of this could be done in survival situations. Despite the website's dedication to wilderness survival, the link here suggest...
I double checked a couple of websites (thanks a lot for the comments to the question) and I'm sure that my compass is not compatible with Australia. As a result of these magnetic variances, the...
If lice are a problem, go back to town, get the necessary supplies, and deal with it the right way. Yes it can be fun to play mountain man and try to source everything from the land. But that usu...
Beyond the ones you have mentioned, there are, Solar Compasses The solar compass, a surveying instrument that makes use of the sun's direction, was first invented and made by William Austin Bu...
I believe the way that it works, is the the time at which it peaks/goes darkest is marked as the day that it happens. In this case, on Feb 26th, according to this page, the New Moon will peak at ...
First you need climb the tree to get them. You need notch the tree to climb it. Then you need a large knife to cut them free. Up in the tree they swing in a circle. You drop the green ones. Many w...
An analogue watch makes a useful compass combined with the sun. I've used this to good effect in cities as well as open country. This link is actually to a rather imprecise method. A more accurate...
Flagging tape is commonly used by hunters to locate their stands and it is important to remove it once you've returned. Bushnell makes a GPS tracking device that stores up to 5 locations/48 hours...
Create a common challenge, a group purpose Backpacking (for me) is a lot about the adventure, excitement and challenges that naturally come along if you try to navigate through unknown situations ...
Living or spending time at higher altitudes will increase your performance via the number of red blood cells you have in your blood. Athletes do this to increase their performance (after they redes...
DIN is always a better connector than the older and inferior yoke format which for some reason is far more prevalent in the US and surrounding countries. There are several drawbacks to the yoke: ...
Keeping grass mowed short in the tropics greatly reduces mosquitoes. They can not take the sun, they are most active at dusk & daylight. They are weak flyers so do not travel far. Sheep graze ...
It looks like there is some truth in it. I don't think that it has to do with the sheep so much as it does with their grazing habits. During the day, mosquitoes like to rest in tall grass or am...
It looks like a DIN valve can be used at higher pressures and has a more secure connection. Since the fitting is more secure, DIN valves allow the use of higher pressures, and are more suitable...
I am a big fan of City of Rocks and the Albion Mountains in Idaho. While some of the peaks are over 8500 feet, there is a lot of hiking at lower elevations. There is a lot of exposed granite and mu...
You might also consider a Z-Rest, which greatly improves on the warmth of a foam mat. It also solves the problem of condensation under your mat, which afflicts both air and foam mats, by the "egg-...
As you were talking about the Alps I suggest having a look around (on Google maybe) to check what kind of alpine and hiking clubs exist near you. At least in Switzerland there are alpine clubs in ...
Most of it will come from having done hard things together. Just being together, say in a classroom, isn't enough, there has to be an element of difficulty. The extreme example of this is men who h...
