Jeff Halka of the Maryland Geological Survey helped lead a search for ancient channels that could be buried under the bottom of the Bay. The first evidence for paleochannels came from boreholes drilled for the building of the Chesapeake Bay Bridge. What Halka and his collaborators found changed our understanding of how the Chesapeake Bay was created.

It came from outer space. A massive meteoroid, at least 2 miles wide, hurtled toward Earth at 60,000 miles per hour. Upon impact it extinguished life within several hundred miles. Its force: 100 times greater than the entire nuclear arsenal of the world. Tsunami waves crashed on land. Clouds of pulverized debris blocked the sun. Then, acid rain poured. Be thankful you didn't call the Chesapeake home 35 million years ago.

In 1938, a line of test boreholes was drilled across Chesapeake Bay between Sandy Point and Kent Island in hopes that a bridge (or possibly a tunnel) might finally be erected that could link the Maryland mainland and its Eastern Shore counties with something faster than steamboats and ferries. A funny thing happened on the way to the Eastern Shore: geologists discovered evidence of an older Chesapeake buried beneath the Bay.
