This paper includes a discussion of the historical development of stratigraphic classification of Cretaceous rocks on the Pacific Coast of the United States, a summary of the faunal evidence for correlating the Cretaceous rocks with the European stages, and all the stratigraphic and faunal data available for 61 areas along the Pacific Coast in Washington, Oregon, California, and northwest Mexico. Many of these data, particularly for Washington and Oregon, have not been published previously. The chart includes lists of fossils that are most useful stratigraphically and presents correlations with British Columbia, Japan, and the western interior of the United States. Included are maps that show the general distribution of Cretaceous rocks along the Pacific Coast. Such maps for Oregon and Washington show occurrences that are not shown on any other published maps.
