Irwin: Happy Father’s Day

I do not know what inspired my father’s interest in rocks. One of these days I’ll remember to ask my mother. All I remember is road trips to find rocks and minerals across the country in our station wagon when I was a child: native copper on the Upper Peninsula of Michigan; agates at quarries along the Mississippi River; geodes and fossils in southern Illinois and a feldspar/schist combination known in non-politically-correct terms as “Chinese Writing Rock” in the California foothills. We would drive long distances down dusty roads to get to the perfect places to find the perfect specimens, and this was how we spent many of our family vacations. My father, who worked at a desk for his day job, enjoyed being out in the sun with a pick and shovel, awaiting discovery.
