Concretions in Worthington, OhioApril 22, 2014

I am sure that you all are probably tired of hearing about the World Fire Sculpture Championship. I am finally finished posting about that. I was up in Columbus this past weekend and discovered a phenomenon that I had never heard about before. They are called concretions and for some reason are all over Worthington. These are basically small to very large round rock formations. They are formed as a hard mass of sedimentary rock formed into spheres with mineral cement before the rest of the sediment is hardened into rock.

They are quite interesting and look like some kind of huge egg fossils or giant bowling balls. Below are a few photos.


This photo shows the scale. The person is my friend BC Collins who told me about this phenomenon.
