Structure Sections of the Fernando Pass Region: Supplement 2 from "Geology of the Fernando Pass region" (Thesis)

Location of area: The Fernando Pass region is located in the low pass between the San Fernando and upper Santa Clara Valleys, and southeast of the town of Newhall. The bounding meridians are Lat. 34° 16' - 34° 22' 45" N. and Long 118° 28' - 118° 32' W. The area includes about thirty square miles and lies between the western end of the San Gabriel and the eastern end of the Santa Susana Mountains. It is bounded by Placerita Canyon on the north and the San Fernando Valley on the south. Refer to Fig. 1 for more general location. Purpose of the work: The work was done in partial fulfillment of the requirements for the degree of Bachelor of Science at the California Institute of Technology. The essential purpose of the work was to gain a more detailed knowledge of the stratigraphic and structural relationships of the rocks in the region. Field work: The geology was plotted in the field on United States Geological Survey topographic maps. The rock exposures were traced on foot and locations were determined by topographic features and by Brunton Compass shots. Dips and strikes were carefully taken with the Brunton Compass and Clinometer. Four days preliminary work in the fall of 1937 and twenty-one days during the spring of 1938 were required to complete the field studies
