Great Lakes Now Presents: Rockhounding with Chris Cooper feat. Yooperlite!

Join Great Lakes Now Host Anna Sysling and Chris Cooper of Great Lakes Rocks & Minerals for a fun, educational and engaging live event all about rockhounding in the Great Lakes! This time, they'll focus Yooperlite--what it is, why it's special and how to find it!
Our featured guest for this event is Erik Rintamaki, who years ago, discovered a rock that glows under an ultraviolet light. Without knowing what it was or why the rocks glowed, he named them “Yooperlites."

This guy did not discover "Yooperlites" I am a geologist and these rocks have been around forever and they do not just occur in the great lakes. This guy commercialized it and put some whacky name to them. They are syenite rocks rich with fluorescent sodalite. They are found worldwide. The name "Yooperlite" is not recognized in the world of geology.
