Chesapeake Bay Impact Crater
Drilling will soon begin in the Chesapeake Bay as part of a new study on the site of a 35-million-year-old meteorite impact crater. Since the impact crater was discovered in 1993, scientists have drilled at least 12 holes, mainly to assess the crater’s effect on groundwater supplies. This fall’s deeper drilling is designed to allow a better determination of how fast the meteorite was traveling, its size, effect on surrounding rocks and whether it was an asteroid or comet.
