Since you are closer to the area than me there is a question i’d like to ask.
Heading east on I-40 several miles before you get to Gallup there was what looked like a military base with dozens earth berm bunkers visible from the highway. Do you know what was stored in those bunkers?
It is the location of the former Fort Wingate which has a checkered past with the control of the Navajo’s for the “long walk” to Fort Sumner after the Civil War and later control of them after they returned.
In the 20th century Fort Wingate supplied 100 tons of Composition B high explosives to the Manhattan Project for use in the first Trinity test and became an ammunition depot “Fort Wingate Depot Activity” from World War II until BRAC closed it in 1993. Environmental cleanup of UXO, perchlorate and lead as well as land transfer continue to the present day.

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).
