Stratigraphy
Formation:Raging River
Stratigraphic resolution:bed
Stratigraphy comments: Formely included in Puget Group, but regarded as distinct due to lack of coal facies. Oldest sedimentary rocks in the Tiger Mountain-Taylor Mountain upland area. MacNeil (written communication) stated that there was little doubt this is a middle Eocene fauna. Probably equivalent to part of the McIntosh Formation of western Washington.
