The field work was done at a point some twenty miles to the southwest of Pasadena, California, from which city the spot may be reached by driving west on Foothill Boulevard to the town of Sunland, and there turning to the north. The area lies almost directly to the north of Sunland, and extends from slightly to the west of Ebbie Canyon approximately one-half mile to the west, and from the northern edge of the Tujunga Wash somewhat more than one mile to the north, thus forming a rectangle having north-south and east-west running borders. The total area is approximately three-fourths of one square mile.

This paper was written to fulfill the requirements of the California Institute of Technology for the degree of Bachelor of Science. Since the author is more interested in Paleontology than in Field Geology, this area was chosen because of the abundance of fossils in its northern section. This particular small area was selected because it contains a representative fossil assemblage, because there would be ample time remaining after the completion of the field work properly to prepare and identify the fossils collected, and because of its accessibility. It has been attempted to assign a definite age to those beds lying to the north of the Sunland Fault through a correlation of the fossils of this region with those of other adjacent areas, especially of the Santa Monica Mountains.
