comment Dog Breeds for Backpacking and Trail Running
@theJollySin: Usually it's thorns, which can be pulled out and the dog is good to go again. Broken glass can also be a worry, or just sharp rocks.

comment Using the Yosemite Decimal System, how difficult is Everest?
The article you linked to also says that the Hillary Step is class 4. Since YDS ratings are supposed to be defined by the most difficult part of the climb, I think the over-all answer is that the normal route on Everest is class 4.

comment What are the real dangers of climbing at high altitude?
There is a variety of conditions that can result from being at high altitude, through a bunch of different physiological mechanisms. en.wikipedia.org/wiki/Altitude_sickness Two really bas ones are high-altitude pulmonary edema (HAPE) and high-altitude cerebral edema (HACE). Re HAPE, which you asked about, see en.wikipedia.org/wiki/High-altitude_pulmonary_edema

comment When should you carry a firearm when hiking/trekking?
@DJClayworth: And even that probably overstates the danger. I suspect that at least some of these people who got killed were doing something stupid such as taunting the bear.

comment When should you start to train with Campus Boards, Hang Boards and Peg Boards?
Climbing grades are amorphous things. Different people's ratings of the same climb could differ by as much as .5 on the YDS. Even if people agree on a grade, there are many different reasons that a particular climb could have a certain level of difficulty. Different types of climbs are qualitatively different.

No, for black bears a gun is not even an appropriate precaution.

comment When should you use gear to climb a tree?
I don't think fear is a reliable guide. People are often afraid of things that aren't significant dangers (mass shootings), and unafraid of things that are dangerous (tailgating on the freeway). Fear tends to go away with familiarity and repetition; danger doesn't. This is why people take avalanche courses and then go out and get killed by avalanches -- familiarity makes them think it's safe.

comment Mountaineering / glacial traverse: rope-up or go it alone?
I've heard that roping everyone together without having a fixed anchor is falling out of fashion Where did you hear this? It sounds pretty impractical to me. Fixed anchors are typically for near-vertical climbing such as YDS class 5. It takes a long time to set up and take down fixed belays.

comment When should you use gear to climb a tree?
Among rock climbers, it's pretty common to hear of people dying in 20-foot (6 meter) falls if they aren't using a rope, neglected to place protection, or climbed high enough so that their protection didn't keep them from decking. I believe these are mostly cases where the person lands on their head or neck, and their neck gets broken. I'm not saying that you can't get killed in a 10-foot fall either.

comment Trail gun for protection against bears
What kind of bears are we talking about? Polar bears? Grizzlies? Black bears? AFAICT the answer is completely different for the different types of bears. In general, this is the bear's natural environment, so if you feel like going there requires you to shoot bears, you're not doing it right. With the possible exception of polar bears, the main solution is food storage, not firearms. For grizzlies, bear spray may be a secondary measure worth considering.
