Handy, I think you may have solved the mystery.

If that ring with the phillips head screws embedded, ever pressed into a soft surface, you’d expect to find the sort of impression we see in the NASA image.

Good job!

[T. P. Pole]

Yup, I think you got it. That head at 9 o’clock is a dead ringer. Good job.

I haven’t gone through all of the photos the rovers have taken. Have you?

LOL. I have neither the time nor inclination. The idea upthread about this possibly being an imprint made by a phillips screw actually sounds more reasonable to me.

Thank you. Of course we still don’t know the scale of the rover image. But that “tamper-proof” style phillips screw head sure bears a resemblance. You can just imagine the spectrometer moving into position and also making the mark to the left of the screw imprint. And yes, it is the screw head at 9 o’clock that shows that same profile.

Touche’!

That’s exactly what it looks like, an old style surveying benchmark.
