Another cold weather injury prevention tip. Take one asprin and one garlic pill a day. The asprin thins the blood and the garlic makes the platelets less 'sticky' so circulation to the extremeties will be improved.
A number of folks advocate taking a satelite phone. My wife insisted I take one and I regretted it.
-The phone was the single greatest expense of the trip
-The phone was heavy and bulky
-The batteries ran out extremely quickly in the cold - you will want a solar recharger
-I got to hear all about the problems at home which took my attention off the mountain
Books are a great idea. I suggest books that are light hearted and easy to read. I figured that I would use the time for self improvement and brought scholarly books and classics that were either not entertaining or difficult to read.
I brought both synthetic and thin wool liner socks (Smartwool). I rotated the socks I wore daily, drying the damp ones at night in my bag. After a couple of days the synthetic socks smelled like unholy death while the wool did not smell much at all.
My partner brought a small bottle of Gold Bond foot powder. That was genius.
Down booties are worth the weight.
but I do my best to get in shape for the "big one" and since we still have lots of snow in the mountains we even tried the sled with one bag of cement and one box of tiles
