A Walk on the Beach

A Rock Hunt in Lake Huron

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. Here's a video showing polished puddingstones:    • Tumbled Puddingstones

– KINGSLEY NORTH –
Kingsley North is a lapidary store in Michigan's U.P. They make a great cab machine and sell many other brands too. They have a huge selection rough rock, tumblers, grit, jewelry supplies etc. at good prices. I buy most of my coarse grit from here in 45 lb. bags. It's the best price I have found. If you buy using the following link, I make a small commission.
