Welcome to the Drive-by Geology Mileage Site! Here you can match the mile markers on the page to the ones on the road to keep the pace as we drive you north through some of Virginia's most varied geology. On the map, select the road section you'll be traveling through and we'll provide the rest. Just a reminder- this page is only a shell of the information here.

    To really unravel the puzzle, click on individually colored groups of words for definitions, concept explanations, and geologic histories.
