Sometime after Mount St. Helens blew its top, a geology professor took his students on a field trip to the area. He pointed to a layer of black sandwiched between lighter colour strata of a tractor machine cut on the side of a small hill.
He asked his students "How many years old was the later of black strata?"
The answers came back in varying degrees of millions of years.
Then he told them that the layer of black strata was the former National Forest Station parking lot.
