Saginaw Bay fingered by gravity data as ice impact feature

Wow. The cascade of stupefying new discoveries continues. A paper published today in the Journal of Great Lakes Research provides evidence from gravity anomalies that Saginaw Bay in Michigan is a remnant feature of an impact into an ancient ice sheet.
