Three members of Whitemud Formation (Upper Cretaceous): at base white kaolinitic sand, in middle brown and black carbonaceous shale, on top white kaolinitic clay and sandy clay. Murphy's clay pit on south side of Frenchman River Valley near Eastend, Saskatchewan. May, 1964.

Three members of Whitemud Formation: at base white kaolinitic sand, a middle member of brown and black carbonaceous shale and an upper white clay member. Grassy slope on top of Whitemud is covered Frenchman formation and exposures at top of section show the Paleocene Ravenscrag Formation (Paleocene) with the Ferris coal seam at base. Ravenscrag Butte, Saskatchewan. May 1964.
