Yooperlite SasquatchYooperlite is the trademarked name of a type of syenite rock (similar to granite), rich with fluorescent sodalite. It is found predominantly along the shores of Lake Superior. No need to hunt this elusive fellow will stand out in any collection of uranium glass or other glowy things. About 3" tall. Due to the unique nature of crystals and minerals, the actual carving you receive may differ slightly from those pictured.
