I've been to this "base" numerous times. It's on the way to Crystal Geyser. (Which is spectacular when it goes off.) There is nothing going on at
the "base." I've driven through (the gate was wide open one day) and poked around the buildings. Yes, some of them go underground. But, there's
still nothing there but a bunch of old wiring. Ignore the base, it's useless. Go check out Crystal Geyser. It's much more interesting. As far as
the trenching machine goes... at that time I believe that they were busy placing fiber optics cable along the route of I-70.
