comment Where do you place ice screws?
I don't think it's a good idea to start leading on ice based on information from the internet. This is a complicated topic that you want to learn in person from someone who knows what they're doing.

@ShemSeger - That dyno move in the video doesn't look that hard -- if I turn my monitor upside down.

comment Can you tell the gender of a chipmunk from a distance?
@ab2: There are actually species that are so similar that you can't reliably tell them apart by looking at them. In an area where I hike a lot, we have both lodgepole chipmunks and Merriam's chipmunks, and the only reliable way to ID the species is by killing the animal and looking at its pelvic bone.

comment Can you tell the gender of a chipmunk from a distance?
There are lots of species of chipmunks en.wikipedia.org/wiki/Chipmunk , and I doubt that it's possible to answer this without knowing what species you're seeing. Any idea? The variations in size and markings may actually mean that you're seeing more than one species.

comment How much distance is there between True North and Magnetic North Poles?
The distance in kilometers is not what's really relevant for navigation. For navigation, we normally care about the angular difference. That can be as much as 180 degrees in northern Canada.

comment How do I rescue someone out of a crevasse?
Your answer focuses completely on hauling the victim out with a pulley, but that's usually a last resort. I've written an answer that's more of a global overview and that hopefully complements yours.

comment What is a safe distance for large, non-predatory wildlife?
Random data point: There are (non-indigenous) bison on Catalina Island, which has a trail system running from one end of the island to the other. I hiked the trail, and tried to follow advice to keep a certain distance from the bison, but it just wasn't possible sometimes, because there wasn't enough room. They basically just looked at me as I walked past.

comment Protection from rain - running vs. walking
As a practical matter, what we care about is not the number of drops that hit us, it's our ability to maintain our body temperature. When you run, you generate more body heat.

comment What are the dangers of descending/rappeling very quickly?
I see, he was giving a fireman's belay. But I still don't think this has much to do with the safety concerns involved in the question.

comment What are the dangers of descending/rappeling very quickly?
It seems like you're mixing up two different things. Taking a fall with a belayer to catch you is a completely different thing than rappelling, with qualitatively different safety concerns.

comment What are the dangers of descending/rappeling very quickly?
The heat is distributed over the whole rope, so it seems unlikely to me that it would burn through. A very, very common reason for fatal accidents is rappelling off the ends of the rope. It seems likely that going fast would increase your chances of not noticing that this was going to happen until too late. Even if you are in the habit of tying stopper knots, there may be times when you forget. Another possible problem is getting banged around, which causes you to lose your grip on the brake strand, causing death unless you use a Prusik backup. Maybe more likely if you're going fast.

comment What micron level is needed to properly filter viruses from water?
"Virus" originally meant anything that could cause disease. The modern usage "virus" is an abbreviation of "filterable virus," which means something that can still cause disease after passing through a filter. In other words, the fact that you can't filter them out was originally the definition of a virus. If you want to kill viruses, you can use UV (steripen) or halogens.
