The Chesapeake Bay impact structure is a late Eocene complex crater that was excavated 35 Ma ago in a continental shelf environment at the Atlantic margin, in Virginia. It is the largest impact structure in the United States and the seventh largest on Earth. It has an average diameter of 85 km and is centered near Cape Charles. The scientific well Eyreville B drilled within the framework of the International Continental Scientific Drilling Program (ICDP) penetrated the deep crater moat 9 km from the center of the structure. Core holes drilled in impact structures are especially suited for investigations of the influence of lithological heterogeneities on petrophysical properties and the thermal field.
