comment Will drinking lots of water in the day(s) prior to a long trek mean I will need less water on the trek?
I spend the whole day in air-conditioned office, so, naturally and unfortunately I drink less water than I am supposed to. This seems to be based on urban folklore that people need to drink more water than they would drink due to the natural sensation of thirst. Not true. ajpregu.physiology.org/content/283/5/R993.full

-1 because this propagates multiple myths about water. See lightandmatter.com/article/hiking_water.html , especially the section "Myth: caffeine causes dehydration."

Sorry, but -1 because of this: The key to optimal hydration is little and often, because too much and your body will expel it, but too little and you become dehydrated. There's no way to avoid this mechanism. This is just propagating urban folklore. Before you get dehydrated, you will experience overpowering thirst.

@Liam: your recommended intake is 2.7 This is false. See Heinz Valtin, "'Drink at least eight glasses of water a day.' Really? Is there scientific evidence for '8x8'?," Am J Physiol Regul Integr Comp Physiol 283: R993-R1004, 2002. ajpregu.physiology.org/cgi/content/full/283/5/R993

comment Is it safe to drink snow?
Are we talking about a backcountry area, or a populated one? Mountaineers routinely melt snow for drinking water.

comment Hypothermia Prevention - Post Ice Water Fall
Get ANYTHING on the head to retain heat. This seems to be based on the urban folktale that people lose a disproportionate amount of heat through their head. Studies have shown that you lose heat through bare skin at basically the same rate (per unit area) all over your body.

What do you mean by "32-10 degree weather?" Is this the same as 10 to 32 degree (Fahrenheit) weather?

comment What is the proper etiquette for back country camps with assigned spaces when people take a different site?
Where is this? First time I've ever heard of reserving a specific camp site in the backcountry.

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.

comment Can you tell the sex 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 sex 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.
