Thompson</figcaption> </figure> <p>Around the Fourth of July, I usually visit my parents and participate in a geological family tradition that is pointless to the extreme and yet addictive and fun. Mom and Dad live on <a href="http://www.lakeleelanau.org/">Lake Leelanau</a> near Traverse City, Mich. The lake is about a dozen kilometers long and a few kilometers wide. It&rsquo;s a great place for water-skiing, fishing, jet-skiing and kayaking. We do some of those things, but we also wade along the shore behind my parents&rsquo; house and search for <a href="http://www.petoskeyarea.com/petoskey-stone-73/">Petoskey stones</a>, the state stone of Michigan.</p>
