I am not sure about that specific site, but my assumption would be old Titan II silos, which are all over the place in NM. I toured one outside of Roswell a couple of years ago that a guy turned into a house.
If it’s active, it’s probably the Minutemen missiles. I’ve seen them driven on I-40 before (poorly disguised).
Freeper Cedar Dave at reply #177 provided info. It’s Fort Wingate.
That is interesting about the old Minutemen silos. I wish I had known what to look for to see them .
Not Minutemen locations - just old high explosive bunkers used until decommissioning in 1993.
