Answer A: Should I do exercises for finger strength as an intermediate, heavy climber?
You could try adding in a few bouldering sessions if you're mostly doing roped climbs. I find that bouldering strengthens the fingers much more than roped climbing, simply because it's higher-intensity movement on (generally) worse holds. It's a good way to condition your fingers &amp; get better at...

Question Is pouring boiling water into a plastic Nalgene bad for you?
I've heard that pouring boiling water into a Nalgene-style bottle is either completely fine or definitely going to kill you. Which is it? Are there any scientific studies demonstrating exactly what happens when you pour boiling water directly into a Nalgene, and how bad this could be for a person? ...

Answer A: What is the point of belay glasses?
Belay glasses are (in Europe) so common that they are basically now part of the standard gym/crag equipment, just like an autolocking belay device. In some places, it can be rare to see someone without a pair on. The primary benefit is comfort for the belayer: you have a much more relaxed neck posit...

Answer A: How to counter bindings getting loose on MSR Lightning Ascent snowshoes?
Some things you can try to hold the boot in place that work for me: Strap the toe, then the heel. Strap the rest of the foot straps. Then, re-tighten the toe &amp; top straps so they are really tight. It helps to think about pushing your foot back into the heel strap. Really pull on the straps. You...

Question Is this image of a skier skinning up a very steep slope rotated?
In another question someone posted a photo of a skier going up an apparently extremely steep slope on skins. This slope looks so steep that skinning would be really difficult (especially on an icy slope without ski crampons), and the mountains in the back seem "off". Is this image rotated or altere...

Answer A: Crevasse rescue with knots in the rope
In a 3:1 (Z-pulley) haul, the victim's rope is used for hauling directly. As you point out correctly, a surface rescue is impossible if you have knots in the rope, since the rope is under tension and you cannot untie the knots. However, you can also drop a different strand of rope down to the victim...

Answer A: Is "Short roping" "Death Roping"?
Short roping is an advanced technique, but it is a necessary one to progress quickly and safely in the mountains. As with most techniques, knowing when to apply it just as important (or more) as the technique itself. The safety in short-roping comes from three main ingredients: Coaching the climbe...

Question Do electronics interfere with avalanche beacons?
I have been told that electronics can possibly interfere with avalanche beacons (cell phones, radios, etc., but even flashlights). Is there any truth to this? A source would be helpful, ideally from a beacon manufacturer themselves. If this is indeed the case, how large is the impact: would it slow ...

Answer A: Are my climbing shoes worth repairing?
These shoes are pretty far gone. At the very least you'll need a new toe rand in addition to the resole, which is going to cost you a significant portion of the price of a new shoe. Your shoes may even be too far gone for any repair at all. Treat this as an opportunity: it's unlikely your first pair...

Answer A: Is there any evidence that attaching a biner to both seat and leg loops results in a 3-way load?
All harness manufacturers instruct users to put carabiners through the belay loop and not the tie-in points. Petzl has it in their manual: Black Diamond's Director of Global Quality Kolin Powick (who does much of their gear testing) has this to say: &#x201C;You should only ever have a carabin...

Question How to painlessly remove gunk left by tape gloves?
After using tape gloves for crack climbing, I always have some tape gunk left over on my skin. While it doesn't hurt and goes away a few days of rigorous scrubbing, it doesn't look super great at the office on Monday morning. How can I remove this gunk left on my skin? I'm looking for something tha...

Answer A: Why are climbing shoes usually a slightly tighter than the usual mountaineering shoes?
I'll address the mountaineering viewpoint (as opposed to the other good answers about the climbing viewpoint). Mountaineering usually involves covering a lot of distance over a bunch of different terrains: flat trails, scrambling/climbing, snow/ice, etc. A mountaineering boot thus needs to be able t...

Question How does weather affect an altimeter watch?
I really love wearing an altimeter watch while in the mountains. I know that it's affected by weather, but unfortunately I don't actually know how it is affected. This usually causes me to ignore the altitude readings entirely when the weather is unstable (and thus altimeter readings are inconsistent...

Question What would happen if I use a USA (GMRS/FRS) two-way radio in Europe?
This question is the opposite from this one: What would the consequences of using a US two-way radio (GMRS/FRS) in Europe? I know Europe has their own frequency range for two-way radios (PMR), but for the moment let's remove buying new radios from the list. Does anyone else use the same frequencies ...

Answer A: Belaying two seconds?
While belaying two seconds at once using the method ShemSeger pointed out is my favorite, it does take a fair amount of experience so I would not recommend it to someone climbing for the first time with two seconds. If you're just starting out, I recommend you use the Caterpillar technique: You lead...

Answer A: Site with statistics of mountaineering accidents
The American Alpine club publishes this data for North America annually, though it's unlikely to cover all accidents. One of the best visualizations of this data I've found is from Steph Abegg: Mountaineering Accident Statistics and Mount Rainier Accident Statistics.

Question How much does a full/empty jetboil canister weigh?
I have a bunch of partially-full Jetboil canisters from various trips, and I'm trying to figure out approximately how much fuel is left in each of them. How much does a full canister weigh (fuel + canister), and how much does it weigh when it's empty (canister only)? (For reference purposes, I thin...

Answer A: V-threads (Abalakov): How many holes are too many?
Will Gadd's book Ice &amp; Mixed Climbing states that if you mess up the first attempt at a V-thread, start over in clean ice. This includes if your screw holes intersect only partway down the hole, the two holes didn't intersect, or the distance between the holes isn't large enough. Practicing makin...

Answer A: What are the rules to grade sport climbing single pitch routes?
I would argue you've left off the most subjective of metrics, but the most useful: similarity to other routes in the same area. I don't think there's going to be a single equation to grade a route. You'll have general rules of thumbs that hold true (more holds = easier, more overhang = harder), but ...

Question What information to leave with your emergency contact?

Answer A: Lowering off from anchors vs. rappelling after a climb?
This, probably more than any issue in climbing, has generated more discussion, heated debates, and vitriol (especially on the internet) than any other issue in climbing. Both sides (lower vs. rappel) are equally ardent in their belief that their way is the One True Way. Unfortunately, both sides are ...

Answer A: An adjustable length knot for 2 lines and a carabiner for easy suspension
The clove hitch is probably what you're looking for. You can even tie it directly on the branch/beam/bar without worrying about adding a carabiner. You could also tie it to the carabiner, adjust the length, and clip the carabiner to something else. The clove hitch is one of the most under-utilized c...

Answer A: Knot to turn cord into loop (load bearing)
I alternate between the double fisherman's (which everyone has already talked about) and the flat overhand. Lately I've been leaning towards the flat overhand. The benefit of the flat overhand is that it's much easier to tie, inspect, and (most importantly) untie after it's been loaded. When properl...

Question What are creative uses for retired carabiners?
I seem to have accumulated a good number of carabiners that, while probably still safe, I won't climb on anymore. They might be worn, of questionable origin, or just plain made obsolete by an upgrade. What are some creative uses for these carabiners? I already have plenty of shoe and leaver 'biners,...

Answer A: How should a climbing rope be stored?
Completely personal preference. The only thing to do are keep it out of the sun (check), dry (check... I hope), and away from corrosives and other sharp things (definitely check). I usually store it in the rope bag in whatever shape it was last used. Generally, that's flaked out (make sure to tie th...

Answer A: How high to climb before clipping on a sport climb?
Petzl does recommend this for the second bolt: Clip the second bolt at waist level; this reduces the amount of rope out and thus helps prevent the climber hitting the ground in case of a fall before making the clip. (Section F, second panel.) I think that's generally good advice for clipp...

Answer A: Is a tarp necessary if you have a tent with a rainfly and a footprint?
You do not need a tarp in addition to the rainfly of your tent (that's what the rainfly is for). While it's always nicer to pack up a dry tent instead of a wet one, as long as you air dry the tent when you get home you'll have no problems with damaging the rainfly. If you do not dry your tent at hom...

Answer A: Replacing rope/cord/tape/slings on protection gear
For cams, Black Diamond recommends: With occasional use: slings should be replaced every 5-8 years With frequent use: slings should be replaced 2-5 years. This sounds like a good policy for any other soft good (from tricams to harnesses). As you mentioned, harsher use or any sign of damage can si...

Answer A: How to pull one's partner from a crack/crevasse when skiing?
First, see my comment above. Get some professional instruction. Seriously. To answer your points directly: Build a snow anchor, then transfer the load to your anchor. Holding your partner's weight for the entire duration of a self rescue would be a bad idea. Building an anchor is independent of wh...

Question Do mountains really make their own weather, and if so why?

Answer A: Roping together on an icy path?
Roping up would be a bad idea. A good rule of thumb is that you should only rope up if you can place protection between climbers (i.e. attach the rope to something). Glaciers are a different story, but that's not where you're going. Many accidents have occurred when one rope mate falls and takes all ...

Answer A: Planning a Trip with strangers
While there's always more uncertainty in climbing with someone you don't directly know, don't discount finding partners online altogether.

Question Hauling a pack during climbing
Generally when doing multi-pitch climbs, I prefer to just climb with a light pack. However, sometimes that's just not possible and the pack(s) must be hauled instead.

Answer A: Can Primaloft One be Layered?
Yes, you can always add layers to stay warmer. Exactly how much warmer isn't really possible to figure out, as different jackets put their insulation in different places (e.g., more in the torso/arms/hood). Using multiple layers has the benefit that you can take off only some of your insulation if y...

Answer A: What Rope to purchase?
Short answer: For your first rope, none of these numbers matter. Any 60m dynamic rope around 10mm diameter will be fine. Get the cheapest one of the three, and buy a rope bag to keep it clean. Get some good instruction and enjoy climbing outside!

Answer A: Micro-Fractures in Climbing Equipments
This is sadly a very persistent myth that has been around rock climbing for far too long.

As a side note, the fact that this group decided their gear was unfit to climb on, yet felt ...

Sleeping with the socks on your torso is the most effective method I have found, and it does not require anything you wouldn't already have.

Answer A: How safe is the bowline knot in different situations?
In addition to zoul's excellent answer, the Bowline has another drawback in that it can come loose (or even undone) after repeated load/unload cycles (i.e. weighing and unweighing the rope). This means that the bowline is not as good as the figure-8 to use to tie-in a climber, especially for multi-p...

First, prevention is going to give you the best bang for your buck. Make sure you dry your shoes properly between uses by hanging them out, and don't keep them in a bag/trunk/confined space.

Unfortunately nail polish would probably gunk up the locking mechanism. I wouldn't put nail polish on any moving piece of a carabiner.
