Crowfoot Formation

The Crowfoot Formation is a stratigraphical unit of Frasnian age in the Western Canadian Sedimentary Basin.

It takes the name from Crowfoot Creek, a tributary of the Bow River and was first described in the Royalite Crowfoot No.

[2] The Crowfoot Formation consists of anhydrite, silty dolomite, with minor shale.

[1] The Crowfoot Formation is typically 4 metres (10 ft) thick, but can reach up to 38 metres (120 ft).

[1] It is equivalent to the Calmar Formation and part of the Graminia Formation in central Alberta and to the Torquay Formation in Saskatchewan, Manitoba and Montana.
