edit1: Some more photos of this selfsame rock through a micro scope (somewhere between 10x and 45x, didn't write it down)

and another feature I discovered: the rock has a slickenside which i can't really show on a photo. basically one of the sides is beat up into sand and polished. the whole rock unit was pretty beat up, so i'm not super suprised but it's cool

edit2: ok i tried to capture the slickenside
