Anyone care to guess where these balls are? Hint: sandstone
Any geologists out there care to explain how these things formed?

Those are "cannonball concretions," kind of like pearls made from sediments. First something forms a nucleus, then layers build up around it while it's all still soft and muddy. Add a few million years to dry out and harden, and you get... big balls.

That's insane! Those are the weirdest geological formations I've ever seen. There like crag tumors. This looks like a case for Erin Brocovich-

Scroatum?????
I must say however that I find Crazyfinger's picture deeply disturbing, although I have a tough time putting my finger on WHY.

Mungeclimber, I don't think Diablo, though I have seen some smaller versions on Diablo.

Not Diablo.
More hints:
It's to the West of the freeway. The stretch between Lost Hills and Los Banos in CA. Named after a horse theif.

Same here, Piton Ron. The pic from crazyfingers had me scratching my head.....and then it came to me.
She's wrestling an egg from the ovary of Mother Earth to be rolled down the mountainside to explode into a billion fragments that will constitute the next Big Bang which will create a new parallel universe.

Here is an answer from a very famous Geolgist. Can someone clear up where they are?
Marty: I don't recognize this locality, but as someone said on the thread, these are concretions. Unusually large to be sure. If you find out the exact locality I would like to know. There are lots of rocks between Lost Hills and Los Banos that would host these concretions.
Best, Casey
