This historical shot from the air was posted recently. Everyone in the comments was saying they couldn’t see an obvious UAP where the base was built and I couldn’t disagree more.
I see a very clear saucer shape and a bubble or dome in the center. All aligning exactly where the base was built. There is even a slice in the rock face adjacent like it was clipped during the crash and years of erosion have exacerbated it. This run off like covered the craft over many years but the outline can still be seen. It’s also strange that this location is almost dead center in the middle of the continent… maybe some sort of waypoint or point of navigational importance.
