My Last Rock Hunt of the Decade

Come along on a Lake Huron beach rock hunt. You'll see lots of Petoskey stones and puddingstones as well as other rocks and fossils. The two main rocks I collect in this video are Petoskey stones and puddingstones. Both rocks are found mainly in Michigan, although a few may be found in some of the surrounding states. The Petoskey stone (Hexagonaria percarinata) is an approximately 360 million old fossilized coral. It is the state stone of Michigan. Petoskey stones are calcite which is very soft, approximately 3 on the Mohs scale. Since they are so soft, they can be polished by hand. See this video for polishing instructions:    • How to Hand Polish a Petoskey Stone   Puddingstones are a conglomerate stones comprised of red jasper and chert in a quartzite matrix. They are found in larger numbers on Drummond Island and St. Joseph Island in Canada but also across much of the lower peninsula of Michigan. They were called puddingstones by British settlers who thought they looked like a boiled suet pudding with berries.
