Adjust the contrast to bring out the symmetry.

And the rock monster tentacle :

Notice the sheared off cross section structure
sticking right out of the ground.

This is all a joke, right? You couldn't possibly be yet one more of
those pseudoscientists who think that because they have given something
a name, it must be that thing they named it. That is, you say that
something looks like a "rock monster tentacle" (and that is so funny!)
therefore it must be a "rock monster tentacle".

I think there is more weirdness going on at your keyboard than there is
on Mars.
