Yooperlite

Yooperlites were discovered in 2017 by Erik Rintamaki, who gave them their regional northern Michigan name. This makes them a relatively new discovery, but they aren’t exactly new to the state.They’re made up of mostly syenite rock, which is similar to granite, which means the rock looks like any other dark stones or typical gray rock, but there’s a twist. Yooperlites are rich with fluorescent sodalite, which glows a vibrant orange or yellow under Ultraviolet Light.
