The Chesapeake Bay impact crater is a buried impact crater, located beneath the mouth of Chesapeake Bay, United States. It was formed by a bolide that struck the eastern shore of North America about 35.5 ± 0.3 million years ago, in the late Eocene epoch.

Aug 15, 2019 · About 35 million years ago, an asteroid traveling nearly 144,000 mph (231,000 km/h) smashed into the Atlantic Ocean near the modern-day town of Cape Charles, Virginia.

Jul 1, 1999 · About 35 million years ago, a large comet or meteor slammed into the shallow shelf on the western margin of the Atlantic Ocean, creating the Chesapeake Bay impact crater.

Oct 28, 2015 · About 35 million years ago, during late Eocene time, a 2-mile-wide asteroid or comet smashed into Earth in what is now the lower Chesapeake Bay in Virginia. The oceanic impact vaporized, melted, fractured, and (or) displaced the target rocks and sediments and sent billions of tons of water, sediments, and rocks into the air.

What and Where is the Chesapeake Bay Impact Crater? For the first of these four themes, David said: “Starting off, there’s been a long history of this investigation” into the possibility of a meteoric impact hitting the Chesapeake Bay.

Jun 1, 2023 · About 35 million years ago a meteoroid 2-3 miles wide swooped through the Earth's atmosphere and blasted an enormous crater into the continental shelf in what’s modern-day Virginia. The ancient impact has been buried beneath 1,000 to 1,500 feet of rocky debris, sediment, and marine deposits.
