Ummmm. Having read it, I am very litte the wiser. My only knowledge of geology, the formations after the last play of the glaciers, is what I've seen here and there across Canada. Impressive, the size and odd formations the rocks and hunks have become. But never took the time to delve into the when's and how's. Early years were kinda full of school, farm and black-sheep stuff, then later lots of getting by in life (military), marriages, now grand-kids, and still more life. With a lot of electronics technology and engineering scattered through-out.

Sorry.
