These fluorescent sodalite rocks are found along the shores of the Great Lakes and are especially popular in the Upper Peninsula of Michigan and the shores of Lake Superior. Erik Rintamaki of Michigan’s Upper Peninsula first spotted something unfamiliar and intriguing along the shores of Lake Superior under the setting sun and evening sky.
Erik named these fluorescent sodalites “Yooperlites,” and caught the attention of geologists, mineralogists, rockhounds, educators and just about anyone who had lived in or visited the Upper Peninsula. The origin of the name “Yooperlites” is the abated abbreviation of “U.P.” for Michigan’s Upper Peninsula. “Yoopers” are the area’s colloquial citizenry. “Lite” refers to the rock’s fluorescent properties from sodalite.
