The control rooms (and personnel quarters) I explored were placed at a slightly higher elevation than the bottom of the missile silos themselves, but the damp nature of a non-conditioned environment (conditioning stopped when they abandoned the silos) was evident everywhere.
Silos used to be easy to spot here. Electrical lines going to the middle of a bare prairie land and stopping were the obvious sign of a silo complex. They worked on a combination of commercial power, generator and battery bank. The battery banks were huge but were the power of last resort. Similarly the diesel generators were large with multi-thousand gallon tanks to feed them.
With decommissioning, much of the silos has been salvaged so that there is little left other than the underground rooms and silos, themselves.
I have a daughter. I tell her, "911 is what you dial after you're raped. 1911 is what you should have before they try."
