The phrase “older than dirt” labels something as exceptionally old. Deep time is the term scientists use for the billions of years of Earth’s history. Both terms proved apt In researching the geography of my home in eastern Fauquier County. It is situated in the Culpeper Basin, a geological formation created about 200 million years ago by the forces that also created the Atlantic Ocean: plate tectonics. I created this short video to visualize the history of the Culpeper Basin.
