Mozarkite Stone.

I have never heard of a Portmanteau word. A combination of two or more words like > MO (Missouri) Zark (Ozarks) ITE (meaning rock). MOZARKITE. That is how they named this rock and made it their State Rock in fact. It is a chert/flint. Awesome color combinations in this rough. -WET pic.-(3"x 3"/3.4 oz./7mm thick) no fractures
