Of course, Gary was a collector of not only lots of rock but Indian artifacts as well. Walking our GSD Lily that afternoon, Leonard had found an interesting rock which he thought had a fossil embedded. Mr. Science identified it as Chert. Chert is a microcrystalline or cryptocrystalline sedimentary rock material composed of silicon dioxide (SiO2). It occurs as nodules, concretionary masses, and as layered deposits. Chert breaks with a conchoidal fracture, often producing very sharp edges. Early people took advantage of how chert breaks and used it to fashion cutting tools and weapons. The name "flint" is also used for this material. Gary presented Leonard with a genuine arrowhead from his own collection.
A few years earlier I had taken a somewhat larger role in instructing younger family members in Indian lore. Showing Leonard some native wildflowers in my garden, we happened upon Canadian Bloodroot. Naturally, an inevitable question arose. The sap of this beautiful spring wildflower was indeed red. Unfortunately upon showing the evidence I daubed some on the Grandchild while sharing a few stories of the warriors of the Lakota Nation. It seems at least one female member of the family did not appreciate me "indoctrinating innocent youth in warlike virtues". Indeed, I was properly chastised but one must admit they are beautiful flowers....:)
