comment Avoiding tangles when leading on double ropes
I had to laugh! I have spent some time on a face with the sun setting, untangling double ropes.

It's possible, but I don't know how exactly. There might be some free apps. There are several commercial, such as Grib Explorer (ocens.com/GRIB-Explorer-P212.aspx). NOAA has the data format on their web site in case you can write an app for it.

comment Washing dishes with seawater or freshwater?
Coastal seawater sometimes has harmful organisms from sewage and animal waste -- enough for beach closures. I don't know any statistics or specifics. Just because it's salty does not mean bad stuff won't grow in it.

comment Washing dishes with seawater or freshwater?
I agree. We definitely should not imply that it's "the norm" to use untreated water for food, drink, or dish washing.

comment Do bag liners add the same warmth value to all sleeping bags?
It seems like it would depend on some other factors. For example, if the liner is porous and the sleeping bag is porous, then the liner will have less insulation in the wind. If the line is thin, then it will have less insulation on the snow (on the bottom), at least in the case of no or little insulating pad, than it would on dry ground because of the greater temperature differential and, as you mentioned, it changes physically under body weight.

comment Do cross-country skis need to be broken-in?
That's possible, I'm not sure. The snow temperature and texture might have more effect than that, as well as the ski width.

You can probably add more than 15 degrees by wearing a bunch of fleece to bed (as long as it's dry), in case the liner doesn't work well.

comment Does eating snow help dehydration?
This looks correct to me (except it assumes 100% digestion efficiency, and that doesn't alter the conclusion). Eating snow definitely hydrates. It also shows that eating 500ml worth of ice/snow could drop your body temperature around 1/3 of a degree (C) in the short term. This might be significant if you're where you need to eat snow -- just something to keep in mind.

I filter or boil it before I drink water from melted snow.

Use mustard -- it won't go bad. :-)

comment Is it safe to camp in the desert without a tent?
In the Grand Canyon I'd worry about rain more than animals. Afternoon thunderstorms are not uncommon.

comment Mountaineering / glacial traverse: rope-up or go it alone?
I agree. Definitely rope up if you're not traveling alone. You cannot always see a crevasse. If weight is a factor, you can get by with an 8mm rope.

comment Driving tent pegs into rocky ground
If tent pegs don't hold, use rope tied to rocks and/or trees/bushes.

comment How can you prevent kids getting lost at night while camping?
Let 'em run! Keep an eye on them from a distance, but natural fear will probably keep them around, and can help if they need it. Encourage them to push their own boundaries.

comment Thinking about a road trip out West
For 2: Get a Rand McNally Road Atlas ($5-$10 from Walmart), and it will show State Parks you can camp at along the way. It's cheap, legal, and you get a shower.

comment What is a good starter kit for beginning indoor climbing?
I've use tennis shoes sometimes when I didn't have climbing shoes with me. It's hard that way, but they work.

You can boulder (low climbing without protection) without any equipment.

comment What are the most important indicators of an high-risk avalanche zone?
@Ross, they are directly associate with very high risk conditions. The "whump" occurs after some relatively powdery subsurface snow has changed into more granular snow, leaving a little space between that layer and a hard slab above. The "whump" occurs when the slab collapses onto the granular layer. This is a highly unstable combination, and is very likely to slide if it collapses on a steep (25-45 degree) slope. As Greg said, it is a sign of dangerous condition in general, not just in the immediate area.

Excellent information!
