The first geologic study of the San Timoteo Badlands was conducted by Childs Frick between 1916 and 1921. Frick launched the reconnaissance as part of an extensive University of California study on the “geologic faunal history of the Pacific coast.” The San Timoteo Badlands of the Riverside and San Bernardino counties, California, are govern by approximately 2,000 m of nonmarine sedimentary rocks that span an interval of time represented by three of the four most recent North American Land Mammal “Ages,” the late Hemphillian through the early Irvingtonian. The main goal of the San Timoteo project was to develop a detailed chronostratigraphy that would aid further investigations into the geologic problems of this region. The approach was to develop a magnetostratigraphy for the entire Badlands sequence and to locate a succession of superposed mammalian faunas that would aid in the correlation and calibration of the local magnestostraigraphy to the MPTS.
