It is {{convert|25|km|mi|abbr=on}} in diameter and the age is estimated to be 91 ± 7 million years ([[Cretaceous|Late Cretaceous]]). The structure is not exposed at the surface. The original crater was partially eroded prior to burial, and lies under {{convert|200|m|ft|abbr=on}} of sediments.<ref name=EIDBSteenRiver>{{cite Earth Impact DB | name=Steen River | linkname=SteenRiver | access-date=15 September 2019 }}</ref>
