Ancient water trapped: The saltwater trapped beneath the Chesapeake Bay crater has been isolated for over 100 million years, making it older than the Atlantic Ocean itself.
An underground layer of water-bearing permeable rock, gravel, sand, or silt from which groundwater can be extracted. An ancient space collision in Virginia disrupted local aquifers, creating a massive, highly salty underground reservoir.
How far north was the ejecta layer from the Chesapeake Bay impact found in Atlantic City?
In what decade was the first evidence of the Chesapeake Bay impact crater discovered?
What unique resource trapped beneath the Chesapeake Bay crater is twice as salty as modern seawater?
Which two modern rivers are diverted sharply around the rim of the Chesapeake Bay crater?
