Rock hunting in the Great Lakes State is a right of passage. The variety of stones, fossils, and minerals that can be found while strolling a beach is astounding. Set against a sky-like blue, this unique Tee See Tee design makes it easier to identify different rocks native to the state. Available in sizes ranging from XS-4XL, this shirt serves as a map, indicating which rocks can be found, and where, throughout Michigan. It can be worn as a guide, or simply as a badge of honor representing our unofficial state hobby (well, there’s also Euchre).
