Inscription.  This rare 4,400 lb. conglomerate boulder is made of irregular-sized jasper pebbles cemented together over millions of years by a finer mix of quartz sand. Often called "puddingstones" (because the stones resemble a British Christmas pudding), Michigan puddingstones are a sedimentary rock first formed in riverbeds a billion years ago in northeastern Canada. During the Ice Age, glaciers pushed sedimentary rocks from northern Ontario to eastern Michigan. Because of its jasper pebbles, this boulder's origin can be traced to a Canadian mountain outcrop north of the St. Mary's River and Sault Ste. Marie.

In the 1970s, Jim Laarman, former GWBHS President, found this boulder a a gravel pit south of Milford. "When I found it to be a puddingstone I thought it would be a great landmark, paying tribute to the power of the glacier that formed many of West Bloomfield's inland lakes and islands, including Apple Island, whose surface form even tells the direction of the final glacier that sculpted out Orchard Lake."

Donated by American Aggregate of Milford, Michigan, 1970s
