the stones and fossils you'll actually meet on a great lakes beach, all 48 of them on one 18x24 poster, sorted by how hard they are to find.

every entry carries its common name, the geology underneath it, its age, and where along the shore it turns up. the rarity bands run from the bedrock you walk over all day to the grails most people never see.

petoskey, charlevoix, leland blue, emberlite, isle royale greenstone, copper agate, trilobite, puddingstone, and 34 more.

18x24 inches, fits a standard frame.

matte finish, so it doesn't mirror in lamplight.

every name and label printed razor sharp.

shipped rolled in a tube, so it arrives flat and unbent.

made in a small workshop on Higgins Lake, Michigan. 10% of every order goes to the Roscommon County Animal Shelter.
