Concretion

So when I was out hiking around with my hubby and no children I stumbled onto these little round balls. I picked them up and they were kind of heavy for their size. I thought hmmm slugs from the civil war...except the civil war occurred no where near my hiking location. Then my hubby found a larger one and informed me they are called Sandstone balls.

I showed my daughter thinking I would have something really cool to tell her. She of course says oh you found Sandstone balls! My utter disappointment mixed with impressed surprise. She already new what Sandstone balls are. I couldn't surprise her with something rather she educated me. They get really big she said, like a soccer ball! I looked them up and its actually called concretion. Minerals mix with the sand and solidify it all together like concrete. Now I want to spot a really large one!
