INTRODUCTION

This is Number 11 of the series of correlation charts being prepared by the Committee on Stratigraphy of the National Research Council (Dunbar et al., 1942, p. 429–434.).
It has been constructed by stratigraphers and paleontologists actively engaged in both field and laboratory research and is not purely a compilation of information sought for in the literature; it has resulted from continuous scientific investigations by some of the men most active in developing present-day conceptions concerning the classification of Cenozoic formations and the interpretation of the geologic history of the Cenozoic era in this part of the globe. As more critical data are obtained concerning the lithology, distribution, and stratigraphic relations of the rock formations and their contained faunas, the interpretations of the correlation and geologic history will become modified.
Two schools of thought exist on the Pacific Coast regarding the classification of Cenozoic . . .
