Stott in 1963.〔Stott, D.F., 1963. The Cretaceous Alberta Group and equivalent rocks, Rocky Mountain Foothills, Alberta Geological Survurvey, Canada, Memoir 317〕 The name is of Cree origin ("maskihkîy"), meaning ''medicine''. ==Lithology== The Muskiki Formationis composed of shale with pebbly mudstone. Poorly sorted sandstone and concretionary beds also occur. In the western areal it becomes more silty.〔 〕
