VIEWING OUR REGION THROUGH GEOLOGY-COLORED GLASSES: THE EPIC TECTONIC SAGA OF THE ROCKS BENEATH OUR FEET*

​ The Mid-Atlantic region showcases two complete “Wilson cycles” of supercontinent formation and destruction. Though Virginia is mostly sedate today (occasional earthquakes notwithstanding), in the past the Old Dominion has been the site of Himalayan-scale mountain-building and rifting fully comparable to the Great Rift Valley of modern day East Africa. Award-winning NOVA geology professor Callan Bentley provides a fascinating tour of our region’s geologic history, looking at the modern landscape and interpreting these ancient tectonic events.
