Where is the crash site that Diana Pasulka and Gary Nolan visited?

Watching a lot of Diana Pasulka content lately and in her book Encounters she goes over an old (1950s?) crash site that she is shown by a Space industry insider who is not named. He is called "Tyler".

She goes with Gary Nolan and apparently this trip is when Gary collects some, not all, of the crash parts(materials?) he is in possession of. The ones that he has confirmed have very abnormal properties for being found on earth.

The details I have collected are:

• Located in New Mexico
• On government land, but none of them are military so I dont think its a military base. Maybe just idle federal land?
• "Around 40 minutes" away from the small town they were staying in. I say small because she doesnt even remember the name. Small town with a motel/hotel?
• Exact location is featured in an episode of the show 'X-Files'. Tyler(the "insider") says someone leaked the location to show production.

The last point seems to be the biggest clue, also indicating it is accessible to the public. Apparently they found the materials with a metal detector.

I've spent too many hours on Google earth trying to get an idea but its just too vast. Anyone have an idea?

edit: few more details
