It's a Brunton compass! :D
I honestly can't tell from this photo, sorry- having trouble even telling if that's soil or sediment coated sandstone.

And the winner is... @mountainwashere. Nice!
it is sand, and the dark sand in the middle are well... something else. darker coloured, and...
lets see if anyone else gets it. but the Brunton is correct!!! :)
Is there a rock underneath that sand? Or is it just darker sand, maybe clay rich?
It almost reminds me of dendritic pyrolusite, but pyrolusite looks more like fern leaves on sandstone. It's also microbe poop.
Good observations!
There is no rock in this photo.
Everything you see are sediments. There is sand and there is darker sand. You are right.
There is also evidence of erosion. In this case fluid flow.
Darker sand is at the base of this "mini-channel" which means the lighter-coloured and lighter in weight sand was eroded away, leaving heavier minerals... I like the microbe poop too... thanks!
Very cool!
