International audience Haughton is a ~24 Myr old mid-size (apparent diameter 23 km) complex impact structure located on Devon Island in Nunavut, Canada. The center of the structure shows a negative gravity anomaly of -12 mgal coupled to a localized positive magnetic field anomaly of ~900 nT. A field...
