The Paleontology and Stratigraphy of the Pleistocene at Signal Hill, Long Beach, California


Purpose of Report: I spent the summer of 1938 studying the stratigraphy and paleontology of the two Pleistocene formations exposed at Signal Hill. Special emphasis in this study was placed on the lower series of sands and gravels from which a large representative fauna was collected. Previous to this no fossils had been reported from this lower group of sediments. It seems desirable, therefore, to record the results of this investigation.

© 1941 San Diego Society of Natural History. I wish to express my appreciation to Dr. W. P. Woodring of the United States Geological Survey, for suggesting the problem and for criticism and advice. Dr. W. P. Popenoe, Curator of Invertebrate Paleontology at the California Institute of Technology, has had general supervision of this paper during its preparation. He has offered many valuable suggestions regarding the faunal relations and stratigraphy of the Signal Hill formations. Mr. H. Hollis Reamer, Mr. John W. Christensen, and Mr. Robert J. Urick of the California Institute of Technology have rendered valuable assistance in the field. The Pleistocene collections of Southern California and the Golisch collection of Recent shells, both at the California Institute of Technology, were indispensable in making comparisons with the fossils collected at Signal Hill.
