Abstract

The area under consideration in this paper is located in the Prado Dam Quadrangle, Riverside and San Bernardino Counties, California. This area is about five miles west of Corona, five miles south of Chino and nine miles south of Ontario. It occupies the central portion of the Prado Dam Quadrangle and includes the following sections: 1, 2, 3, 11, 12, 13, 14, and 24 of the T. 3 S., R. 8. W., S. B. B. & M.; 7, 18, and 19 of T. 3. S., R. 7 W., S. B. B. & M.; and 34, 35, and 36 of T. 2. S., R 7. W., S. B. B. & M. The area may be easily reached by California highways 18 and 71 and U.S. highway 91. Several good roads cross the area and are maintained for the use of oil development and maintenance of power and gas lines. [...]

The purpose of this paper was an attempt to arrive at a reasonably accurate picture of the subsurface structure parallel to the Chino fault both above and below the fault zone and to determine whether or not there is any correlation between the surface and subsurface structure.
