Image Caption: The Chesapeake impact structure is a complex peak-ring crater buried 300 to 500 m below the lower Chesapeake Bay. The crater diameter is 90 km. The age of the structure has been estimated at 35.5 million years. The center of the crater is located near the town of Cape Charles on the Delmarva Peninsula. The impact nature of the structure was confirmed by Wylie Poag of the US Geological Survey and his colleagues when evidence of shock metamorphism was found in core breccia samples taken from depths of 372 to 416 m.
