All the talk about storing tissue and DNA samples (not to mention bodies)
in the ice of Antarctica or Alaska is missing the point that the storage
should be done at much lower temperatures.

Chemical processes of decay no matter the temperature (only at Absolute
Zero, which is unattainable of course, do they stop). For reasons of 
engineering and economics, liquid nitrogen (77 K) is used. That effectively
stops chemical reactions, and the heat of vaporization ensures that the 
object being frozen will pretty much stay exactly at 77 K (up and down
variations are a bad thing).

I believe the original poster was making some points about large storage
facilities in remote areas for other reasons: economies of scale, remoteness
from armed looters, and so forth.
