It comprises the western part of Riverside County and the southwestern corner of San Bernardino County. The area lies about 35 miles east of Los Angeles. It is bounded on the north and northeast by the Sierra Madre and San Bernardino Mountains, respectively. The Santa Ana Mountains and the associated Puente Hills, with the Box Springs Mountains and various connected or detached series of broken elevations, form the curved boundary on the south. The western boundary is a north and south line extending across the open valley a short distance west of Ontario. The Jurupa Mountains, Mount Rubidoux, and several lower elevations are included in the southern part. The area comprises 606 square miles, or 387,840 acres. This survey covers the greater part of the area included within the earlier soil survey of the San Bernardino Valley, California.1 Topographic sheets of the United States Geological Survey were used as base maps in the prosecution of the field work, with some revision made necessary by recent changes in the location of roads or in other cultural features. The partly inclosed valley in which the Riverside area lies has two openings to the west, one in the vicinity of Lordsburg and San Dimas, and the other west of Pomona. These are several miles beyond the western boundary of the area surveyed. They form outlets to Los Angeles and other centers of population....
