Boulder?

Nope!
That's the same stone on top of an AA battery for scale in the second picture (after the jump).

Late posting, as per. I have excuses, but they're boring.
Shot with the MPE-65mm at 5x magnification on the EOS M6 Mk II, on the WeMacro focus rail.
1.5GB of raw files went into this one.
Stacked with Helicon Focus. I used flash to try and keep things sharper, and it does seem to have helped.
I am tempted to get a proper macro flash setup, because the normal flashguns are a bit unwieldy with a subject this small.
