A theory that catastrophe emplaced the Erratics Train of Alberta, Canada, and filled the basin of Lake Bonneville of the western interior United States with sea water, is examined and found consistent with both field evidence collected by the author and published information (Stalker, 1956; Tharin, 1962; Broecker and Orr, 1958; Morrison and Frye, 1965; Mountjoy, 1958). The evidence is found to favour tidal inundation to account for both phenomena, although this explanation has heretofore been wholly overlooked.
