Bruce Mueller

Publication Year: 2010

Bruce Mueller is the rock expert who brought you the very popular Complete Guide to Petoskey Stones.

This is the perfect guidebook for anyone or any family who walks the beach and wonders, "What is this?" Bruce Mueller is owner of the C&M Rock Shop in Honor, Michigan. He holds a master's in geology from the University of Illinois. William H. Wilde is an avid rock collector.
