The Miette Group is an assemblage of metamorphosed sedimentary rocks of latest Precambrian (Neoproterozoic) age. It is present in the Canadian Cordillera from the Lake Louise area of Alberta to the Yukon.[2][3] The Miette rocks include Ediacaran fossils, stromatolites, and trace fossils.[3][4][5][6]
