It is amazing how little we know about what is under our feet, yet at the same time amazing how much has been learned.

For example, I know that the basement rock under my feet used to be at the equator even though I am over 30N. I know that there were volcanoes close by (long ago eroded away), a pluton that may still exist, and that massive ice sheets reached here.
