Here are a few new Yooperlites (3 Billion year old Sodalite) from our camping trip up on Lake Superior
Found on the rocky shores of Whitefish point on Lake Superior , Michigan
These rocks light up orange under both the 395 nm and 365 nm Ultraviolet flashlights : https://amzn.to/3Tffstp
In natural day light they almost look like granite
Location of discovery
I notice they also sell Yooperlites on Temu : https://share.temu.com/3jhfYKgLO5A
