An outcrop of Albian-aged sediments located on Fall Creek, in the Rocky Mountain Foothills, contains an interval of the Viking Formation. The significance of this locality, which was studied by integrating lithostratigraphy and foraminiferal content, is threefold. This outcrop, which can be considered as a reference section, is the first documented occurrence of the Viking Formation. The Viking Formation at this locality is not underlain by the early late Albian Joli Fou Formation, such as in the central plains, but rather by marine sediments of the middle Albian Hulcross Formation/Harmon Member. The distribution of marine sediments associated with the Hulcross Sea are much more extensive than previously documented.
