Michigan State University and the University of Saskatchewan have confirmed the existence of a new, glowing rock along Lake Superior Beach.

The discovery was made by  last summer while he was searching for rocks on a Michigan beach, CBS News reports.

Rintamaki told CBS he often goes out rock hunting, but he was shocked when he first came across something glowing among the pebbles one night last June.

He later named the discovery "Yooperlite".

Rintamaki sent samples to Michigan State and the University of Saskatchewan where they were analyzed for months. The confirmation that a new type of rock had been classified was announced in May.

Michigan State identifies them as syenite clasts containing fluorescent sodalite.

While Rintamaki isn't the first person to find them, he is the first to have them verified.

He's been back to the beach most nights since, armed with a black light to help illuminate the Yooperlites.
