1.CHESAPEAKE BAY IMPACT CRATER
It was formed by a bolide that impacted the eastern shore of North America about 35 million years ago, in the late Eocene epoch. It is the largest known impact crater in the US. It's diameter is85 km (53 mi).
It is the fourth largest verified impact crater on Earth. A large bolide impact created the 100 kilometres (62 mi) diameter crater approximately 35 million years ago during the late Eocene epoch (Priabonian stage). The impactor in this event has been identified as either an 8 km (5.0 mi) diameter chondrite asteroid, or a 5 km (3.1 mi) diameter stony asteroid.
One of the biggest and most famous impact craters in the world is buried underneath the Yucatán Peninsula in Mexico. Named after the town nearby, it was concluded that the impact causing the crater was also caused the demise of the non-avian dinosaurs on Earth. The crater is more than 180 kilometres (110 mi) in diameter and 20 km (12 mi) in depth.
As the oldest known impact craters in the world, it is also one of the oldest large astrobleme that is still visible in the surface. Tied with the Popigai in terms of diameter at 62.9 miles (100 km), it contains the Manicouagan Reservoir. The impact formation is located in the Côte-Nord region of Québec, Canada.
Located in the present day Free State Province of South Africa, Vredefort Dome broke a handful of world records as the largest verified impact crater in the world, the asteroid which hit it owing to the huge size of the crater was the largest ever to hit the Earth, and is the second oldest known crater in the world at 2.023 billion years old (300 million years younger than the oldest).
