Boltysh crater Boltysh crater The Boltysh Crater (Bovtyshka Crater) is an impact crater in the Kirovohrad Oblast of Ukraine, near the village of Bovtyshka. The crater is in diameter and its age of 65.17 ± 0.64 million years, based on argon dating techniques, is within error of that of Chicxulub Crater in Mexico, and the Cretaceous–Paleogene boundary (K–Pg boundary). The Chicxulub impact is believed to have caused the mass extinction at the end of the Cretaceous period, which included the extinction of the dinosaurs. The Boltysh impact likely occurred several thousand years before Chicxulub, suggesting the extinction event may have been driven
Chesapeake Bay impact crater also one of three factors contributing to the sinking of land near the Chesapeake Bay. For example, Hampton Roads is gradually sinking at a rate between per century. This is occurring because of the slippage of the coast into the crater, the reverse effects of isostatic rebound of the crust of the earth from the weight of long absent glaciers north of Maryland, and groundwater removal. Chesapeake Bay impact crater The Chesapeake Bay impact crater was formed by a bolide that impacted the eastern shore of North America about 35.5 ± 0.3 million years ago, in the late Eocene epoch.
