Kotaneelee Formation

The Kotaneelee Formation is a Late Cretaceous stratigraphic unit in the Western Canadian Sedimentary Basin, named for the Kotaneelee River and first described there by C.O. Hage in 1945. Composed of marine shale, sandstone, and conglomerate, it preserves sediments deposited in an ancient marine environment. The formation is about 152 to 305 metres thick and is exposed along the Petitot and Liard river valleys, from the Beaver River to the mouth of the Kotaneelee River. Within the regional sequence, it lies conformably above the Dunvegan Formation, grades upward into the Wapiti Group, and in Alberta is considered equivalent to the Wapiabi Formation.
