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. It is one of the best-preserved "wet-target" impact craters in the world. [3]
The Weaubleau structure is a probable meteorite impact site in western Missouri near the towns of Gerster, Iconium, Osceola, and Vista. It is believed to have been caused by a 1,200-foot (370 m) meteoroid between 335 and 340 million years ago [ 1 ] during the middle Mississippian Period (Latest Osagean to Earliest Meramecian ).
This list includes all 60 confirmed impact structures in North America in the Earth Impact Database (EID). These features were caused by the collision of large meteorites or comets with the Earth. For eroded or buried craters, the stated diameter typically refers to an estimate of original rim diameter, and may not correspond to present surface ...
Less than ten thousand years old, and with a diameter of 100 m (330 ft) or more. The EID lists fewer than ten such craters, and the largest in the last 100,000 years (100 ka) is the 4.5 km (2.8 mi) Rio Cuarto crater in Argentina. [2]
The following tables list geological features on Earth that are known impact events as well as possible, but for which there is currently no confirming scientific evidence in the peer-reviewed literature, impact events. In order for a structure to be confirmed as an impact crater, it must meet a stringent set of well-established criteria. Some ...
A map of Kent Island from 1970. As roads replaced railroads and steamboats into the twentieth century, there was a growing need for a road bridge connecting the two shores of the Chesapeake Bay. In 1952 the Chesapeake Bay Bridge was completed, connecting the island directly to the Baltimore-Washington Metropolitan Area. The bridge completely ...
After firing up Google’s map software to plan a camping trip in Quebec’s Côte-Nord region, he told CBC, he found the curve of what turned out to be a roughly nine-mile-diameter pit near a ...
