For certain contaminants such as Giardia, it doesn't matter whether the water is running fast or slow. You will get infected regardless. So this idea about "fast water" is a myth that is not correc...
What you are specifically asking for is quite rare. That is because any place wet enough to have the kind of grass you want will have trees. There are vast grassy areas in the center of North Ame...
For what purposes? For 'general' purpose, you should be able to get by just fine by making a bight in your line, then tying any knot you'd normally use in your situation using the bight as your lin...
I think this means you are varying the volume of your body too much or holding a full breath too long. Try holding your chest in a more consistent position as you breathe.
You could do two half hitches using a bight in the cord. In fact, I would expect many (most?) hitches to work well using a bight. I do this frequently when hanging a ridge line for my tarps using...
The graph looks exactly like a bunch of graphs in House and Johnston, Training for the New Alpinism, pp. 334-337, except for the scale on the time axis. The ones in House and Johnston are for moder...
The Blake's Hitch tied with with a bight should work okay as well. It is a tree climbing/friction/sliding knot very similar to a prussik or klemheist but without needing a loop for its structure. ...
Stabilizer/Load-lifter/Load-adjuster... Straps Those are stabilizer straps, also known as load lifter or load adjuster straps. You typically have another set of stabilizer straps on your waist bel...
A lot depends on where you live and where you ski, but unless you've got solid enough skiing skills to manage ungroomed terrain at a resort, you'll struggle a lot backcountry skiing in a typical si...
What about the Chilterns (http://en.wikipedia.org/wiki/Chiltern_Hills) Relatively near, though not very high
As you say it is rather flat around there. So you will be quite hard pressed to find any significant hills that close to you. The most obvious area that comes to mind is the Chilterns. Although, t...
AT (Alpine Touring, aka-randonnee) is quickly rising to be the most popular form of downhill skiing. There are still those die-hard telemarkers that will never switch, and they will out distance yo...
You can find grassy mountains in Colorado in the Guanella Pass, but you may find that the air is a bit thinner up there than it is in Scotland: Guanella Pass Another place you'll find mountai...
No, there doesn't seem to be any standard in place for avalanche shovels. Even though an avalanche shovel has to be depended on in a life or death situation, there are plenty of cheap ones out the...
Thinner diameter ropes such as these have a wide range of uses but are not primarily designed for climbing. See this description from Sterling Ropes: These smaller cords can be used in a wide r...
There have been quite a few studies on this. There are various factors that will affect this, these include: Position in the snow: people upside-down sometimes live longer because the brain has m...
Only 1 out of 10 survive Avalanches If you are completely buried in an avalanche the odds of survival are slim, unless you wear a transceiver (beacon), and you have partners that escaped the avala...
There are many discussions going on around this. Just remember the decompression models are theoretical mathematical models, backed by practical dives/research. We implement some rules for safety,...
Firstly, it's very nice to see someone do the eye float thing :) But this should be done on an near empty cylinder (50 bar). Else you are perfectly weighted with about 2kg of air in your cylinder (...
I shall have to call bullshit on this. I personally forgot to hook up my dry suit inflation hose many years ago and sank to 36m (4.6 atm) in cold UK waters. Where I suffered from serious love bites...
You don't mention if you are adding/removing air from your BC while doing this. It sounds like you may be overweighed and compensating by having too much air in your BC. As you breath in you displa...
Firn/névé: Snow consisting of several millimeters sized grains that develop by repeated melting in the sun and freezing over again during the night. Typically occurring in late winter and spring w...
Depending on how strict your definition is... Windrow: The pile of snow along the edge of the road left behind by a snowplough. You could also look at this list or this one. Not every word on th...
Skiiers have many words for snow. Powder Packed Powder Hard pack Ice Glare Ice (If you dig in, you can catch an edge on ice, but not on glare ice.) Crud (Used to be powder, but then it got warm ...
I'm going to assume your question is geared towards high altitude (20,000+ ft) climbing. Haven't done any myself but this topic is covered at length in almost every book written regarding Everest a...
