comment How can you navigate without a compass or GPS
This is just plain wrong. Different species of moss and lichens grow on different sides of trees dependent on a lot of factors. At the northern end of a species' range it may well appear mostly on the south side of trees while other species in the same forest are on the other side or all around depending on local microclimates. Just forget about the moss myth, it will waste your time and keep you from observing the things you really need to pay attention to.

comment Can body-to-body rewarming be used as a last resort treatment of hypothermia?
@Chris: What I was referring to is when hypothermia has progressed so far that the body shuts down blood to the extremities in the last effort to keep the core alive. Toxins then build up in the extremities. The victim can be poisened by his own toxins if the extremeties are warmed first. The person needs to be warmed from the inside out in a medical setting. Keep in mind we're talking about sever hypothermia progressing immenently to death without medical intervention. If someone can drink warm liquid, by all means have them do it, preferably containing fast-metabolizable sugars.

comment What are the key sites to see on a short trip through Oregon?
Wow, that's a lot of stuff for 2 weeks. You'll need a vacation when you get back from this vacation. Also, most of the arches are in UT, not NV. There are lots of beautiful places in OR. Crater Lake? Mt Hood? Lots of other parts of the Cascades? The coast, mouth of the Columbia?

I suppose if the alternative is the person will die, then there is little downside. However, it could actually make things worse for severe hypothermia. At that level, the body needs to be warmed from the inside out. If not, the toxins that have built up in the extremities can get you. This needs to be done in a medical setting. If someone is still concious, get some hot liquid in them, otherwise evacuate if possible.

comment How far is a reasonable distance for someone to hike on their first trip?
Weight training doesn't do much for hiking stamina. You want erobic exercise for that.

comment May hiking in Eastern California
If you don't want to deal with much snow, try going east a little since that will be in the rain shadow of the Sierras. I haven't been to that area in May, so I don't really know, but the White Mountains east of Owens valley might be something to look at. Or maybe even a little further to the area of Wheeler Peak. I think temperatures in the desert will be more moderate then, so that could be interesting, especially if you've never been to a desert.

comment How to create campfire which will burn overnight?
@DonB: I don't remember a episode where lawyers got envolved. Could you elaborate? Even though Les has to manage the cameras all by himself, I find the camera work of Man vs Wild more annoying. The guy pans and zooms way too much while you're trying to watch. It seems to have gotten worse lately so I stopped watching. Dual Survival also seems quite staged at times, although it can be fun to watch the two together. Cody knows what he's doing, but is a preachy prick a lot, and the new guy Joe sometimes does dumb stuff. The previous guy Dave was better.

comment How to create campfire which will burn overnight?
The trick to a long lasting fire is to limit the oxygen to it. Your pyramid stack would do the opposite. You'd get a really roaring fire for a relatively short time for the amount of wood used. Also I suspect Bear regularly attends to the fire during the night. There is a lot of stuff they don't show you. I like Survivorman better. Les does things ordinary people can do (Bear is a former special forces guy), and it's less staged.

comment Minimizing ecological impact of winter-sports in the backcountry
It depends a lot on the snow conditions too. Alpine tundra is the most fragile of the vegetations you mention, but it is also usually covered with the hardest snow. Just 3 inches of hard snow should protect it well enough. Look at your tracks. Are you hitting ground, or is there always a layer of snow under your footprints?
