comment What is the longest time you can go, eating only freeze-dried food?
A normal fit person can go without any food for longer than two weeks, so clearly the two week limit on freeze-dried food is bogus, unless you think eating freeze-dried food is actually worse than no food at all. Take a look at how long people on hunger strikes have lasted. The answer is much longer than two weeks.

comment Flashlight or headlamp for night hiking?
If your headlamp is shining on the top rim of your glasses, then you have a poorly designed headlamp. I arranged the LEDs on my hat carefully so that none of the light gets into my eyes or on my glasses, but the hat rim causes no shadow within the normal field of vision. Having the light forward, like on the hat brim, helps with this. As for a flashlight as a club, the extremely slight advantage is far outweighed by having to carry a large and heavy club. In all the time hiking in my whole life, I've never encountered a situation where a club for defense would have been useful.

comment Flashlight or headlamp for night hiking?
I don't get the part about the brightness of a headlamp effecting your vision. The light from the headlamp shouldn't be shining into your eyes or onto your glasses, and yes, I do wear glasses. If it's foggy, then having a light not near your eyes, like a flashlight, is useful. But in normal conditions I don't see the issues.

comment Walking through a Thigh-high snow
Thigh-high snow and 30 degree slope sounds like a dangerous combination. You're just asking for avalanche trouble. Then the 20,000 foot altitude will make rescue much less likely.

comment What kind of mementos, if any, am I allowed to collect from State and National parks in small quantities?
Actually you can sometimes take rocks. For example, there is a specific rock you are allowed to collect above Diamond Rim in the Tonto National Forest of AZ. There are limits on the number or weight and possibly time of year, but it is specifically legal within the stated limits. Good point about archeological sites. Disturbing those, let alone taking anything, is a serious federal offense in most cases.

comment When to perform a filtering of the water?
A bandanna may filter some bulk crud, but does little to get rid of the stuff that is really dangerous. Bacteria and virus are too small for a bandanna to catch. It might catch some parasites, but I wouldn't count on it.

comment How can I boost morale on long backpacking trips?
I've told people of my experience trudging thru the snow in street shoes uphill both ways, but they don't seem to believe me.

comment How can I boost morale on long backpacking trips?
Tell them to have fun or else you'll make them trudge another 5 miles in the rain to arrive at camp after dark. If that doesn't work, send them to scout ahead left at the next intersection while you quickly take the correct path to the right. Then there are other options envolving mine shafts and steep ravines.

comment Are drop bears dangerous?
I had never heard of Drop Bears before, but they sound vaguely related to the Jackalope of the southwestern US.

comment What alternative topographic maps exist in the USA?
Did you look around at what overlays could be enabled for the USGS maps? The one you show looks rather sparse.
