Hello,
I'm the owner of the VegasHikers.com
Anyway, I believe that you are looking for the F-4 crash site just North of Area 51.
So, this is the crash site.
http://www.vegashikers.com/pic/20171214B/p1.htmlThis F-4D (#66-0227) crashed in 1979 near the North gate of Area 51.
There are hundreds of debris still up on the hill for more than half miles.
If you want to visit there, just be careful with "Camo Dude" (the private security : google it and watch youtube video of them)
The F-4E (#73-1180) crash site which MikeW attached the link (
http://www.vegashikers.com/pic/20171213A/p1.html) was near Tempiute mountain where is about 15 miles NE of the F-4D (#66-0227) site.
And there is another F-4E (#68-0518) crash site about 30 miles NE of F-4D (#66-0227) site.
