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 Earth Impact Database is a database of confirmed impact structures or craters on Earth. It was initiated in 1955 by the Dominion Observatory , Ottawa, under the direction of Carlyle S. Beals . Since 2001, it has been maintained as a not-for-profit source of information at the Planetary and Space Science Centre at the University of New ...
Map of Tangier and its surrounding islands. Tangier Island is located in the Chesapeake Bay in Accomack County, Virginia. The island is composed of three sandy ridges divided by marshes and tidal streams. These three ridges, called West Ridge, Main Ridge, and Canton Ridge from west to east, run parallel north-to-south.

This category is for articles related to, including craters listed in, the Earth Impact Database, which is the scientifically accepted list of confirmed impact craters.. Therefore, listing in the EID is also Wikipedia's consensus definition of a confirmed impact crater or struc
In 1755, the Virginia General Assembly recorded the name "Hampton Roads" as the channel linking the James, Elizabeth, and Nansemond rivers with the Chesapeake Bay. [7] Hampton Roads is among the world's largest natural harbors. It is the northernmost major East Coast port of the United States which is ice-free year round.
The three larger ones in the US either have been glaciated and buried (Manson crater), are under water (Chesapeake Bay crater), or have been subjected to orogeny (Beaverhead impact structure). Therefore, the Weaubleau structure is the largest exposed untectonized impact structure in the US.
This list of Chesapeake Bay rivers includes the main rivers draining into the Chesapeake Bay estuarine complex on the mid-Atlantic eastern coast of the United States, North America. The three largest rivers in order of both discharge and watershed area are the Susquehanna River , the Potomac River , and the James River .
