“Enjoy this short route leading to a unique view into Virginia's ancient past.”— Roanoke Outside
Where did this all come from, you ask? The answer is found in geology. The Antietam Quartzite found at Devil's Marbleyard (Arnold's Valley) is the result of a rise in sea level relative to the land (transgression), over 500 millions years ago, followed by a time were the area was dominated by a pure quartz beach. The blocks and boulders at the Marbleyard have tube-like structures running parallel to one another. Likely, these are the fossilized remains of cavities where a worm-like creature lived.
