Cover Story: The Kentland Crater impact structure is a deeply eroded crater in western Indiana, of which the only remaining surface expression is a limestone outcrop in the crater’s central uplift. To reveal the hidden structure, we conducted a geophysical survey with an emphasis on gravity and seismology. We observed a large, positive central gravity anomaly, implying that the fracturing and porosity present in the initial impact structure was confined to the near-surface and removed by subsequent glacial scouring. The gravity signal reveals an apparent diameter of 10 km, which falls between two previously published diameter estimates, 12 km and 8.6 km. The wide range of size estimates for Kentland Crater emphasizes the ongoing state of research toward understanding crater formation mechanisms on Earth and on rocky bodies throughout the solar system. View this paper
