This is where the gods split the super tough sarsen with a mere flint point, Or maybe it’s naturally occurring flint within the stone, i dunno. ;)
I showed this pic to a friend who knows far more than myself about local geology, I thought flint only formed in the chalk, Not the sarsen too.
Quite an informative piece of info gleaned from such a nondescript piece of rock. ! ;)
