ABSTRACT 
 
 A reconnaissance field investigation of sand and gravel deposits in 10 counties in 
 southern California was conducted from 1962 to 1965. Deposits that were worked 
 commercially and undeveloped deposits of potential economic interest were examined. 
 Fixed plants were visited, pits sampled, and grave! examined in the laboratory. 
 
 Stream deposits, ancient beach deposits, and old geologic formations including 
 sandstone and conglomerate are the principal sources of sand and gravel in southern 
 California. The bulk of sand and gravel occurs in the stream beds, floodplains, terraces 
 and alluvial fans of the major streams. 
 
 In 1966, approximately 66 million tons of sand and gravel valued at about 74 
 million dollars were produced from the southern California counties covered in this 
 report. Commercial operations are located close to population centers; those which 
 produce from stream deposits are located on portions of the stream where a proper 
 blend of material can be obtained. Plants have capacities ranging from 30 to 1,000 
 tons per hour and produce concrete or bituminous aggregate and road base. Data 
 on the individual deposits, including laboratory test data obtained from the California 
 Division of Highways, are presented in a tabulation. The locations and extent of the 
 deposits are shown on an accompanying map.

 INTRODUCTION 
 
 This report is the third of a three-part bulletin on 
 the occurrence of the major sand and gravel deposits 
 in California. Part C includes the results of field and 
 laboratory investigations of sand and gravel in the 10 
 southernmost counties in California (San Luis Obispo, 
 Kern, Santa Barbara, Ventura, Los Angeles, San 
 Bernardino, Orange, Riverside, San Diego, and Im- 
 perial). Thirty-one central counties were discussed 
 in Part B; 17 northern counties were discussed in Part 
 A of this bulletin (180). The area covered in Part C 
 as well as those covered in Parts A and B, is shown 
 on figure 1. 
 
 Purpose. The purpose of this investigation was to 
 obtain the basic information necessary to a statewide 
 inventory of sand and gravel deposits, including the 
 location and extent, geology, and status of commercial 
 development of deposits. 
 
 Scope of investigations. Field investigations of a 
 reconnaissance type were conducted from January 
 1962 to December 1964. New plant operations were 
 visited in 1965 and 1966. The location and extent of 
 the deposits were plotted in the field on U.S. Geo- 
 logical Survey topographic maps scale 1:24,000. Field 
 determinations of the. configuration of the deposits 
 were checked in the office with geologic maps, aerial 
 photographs, and available U.S. Department of Agri- 
 culture soils maps. Samples of representative materials 
 were taken in the field and later petrographic examina- 
 tions were made in the Division of Mmes and Geol- 
 ogy's aggregate laboratory. 
 
 All deposits that were being, or had been, worked 
 commercially, and undeveloped deposits which may 
 be of commercial significance in the near future were 
 visited. Where commercial production was obtained 
 from an extensive geologic formation such as a con- 
 glomerate, only the developed portion of the deposit 
 was delineated. Small deposits (under .50,000 cubic 
 yards), and deposits located farther than 50 miles 
 from a marketing area were excluded. 
 
 The fi.xed commercial plants were visited, operators 
 interviewed, and the pits examined. Portable plants 
 that were in operation at the time of this investigation 
 are noted in the tabulation. 
 
 Descriptions of a number of plants in Los Angeles 
 County were provided by the Southern California 
 Rock Products Association whose assistance helped 
 expedite the field work. 
 
 Mr. Robert E. Frecland, who is in charge of raw 
 materials and land management for Pacific Western 
 Industries, furnished information on the current status 
 of operations and was extremely knowledgeable re- 
 garding potential sources of aggregate. 
 
 The results of standard acceptance tests on materials 
 from commercial operators were obtained from the 
 files of the Materials and Research Laboratory of the 
 California Division of Highwa>s. The results of petro- 
 graphic examination of several deposits were kindly 
 provided by the U.S. Bureau of Reclamation. AV^c wish 
 to acknowledge these agencies' cooperation in making 
 their data available.

 Sand and Gravel in Southern California 
 
 GEOLOGY OF DEPOSITS IN SOUTHERN CALIFORNIA 
 Stream deposits, ancient beach deposits, and older 
 geologic formations have all yielded commercial sand 
 and gravel in southern California. Approximately 75 
 percent of the sand and gravel being mined occurs as 
 stream deposits. 
 
 Stream Deposits 
 
 Most of California's aggregate production is ob- 
 tained from sand and gravel in stream deposits. Cali- 
 fornia's rugged mountains are drained by streams with 
 steep gradients. In flood stage these streams transport 
 huge volumes of sand and gravel that are deposited in 
 channel, floodplain, terrace, and alluvial fan deposits. 
 
 Stream Channel Deposits. Stream channel deposits 
 consist of sand and gravel deposited in stream beds 
 along present stream courses. Most channel deposits 
 are exploited. The reason they are used so commonly 
 is that many California streams are dry for much of 
 the year, and their channel deposits arc accessible and 
 easily mined. 
 
 Materials in these deposits are desirable as aggre- 
 gate for many reasons. The natural abrasive action of 
 stream transport has ground up and removed most 
 
 of the soft weak rocks and concentrated the harder 
 and firmer particles. The particles have undergone 
 some degree of rounding, and are subrounded to well- 
 rounded, a physical attribute that makes them desirable 
 for use in concrete. 
 
 Most channel deposits are replenished by seasonal 
 floods except in portions of the streams downstream 
 from dams. Overburden is rarely present, but high 
 waters may bring in silt, clay, and wood debris to 
 cover parts of some channel deposits. The maximum 
 size of gravel gradually decreases downstream in the 
 streams with long reaches, and commercial production 
 is concentrated in the deposits where a proper blend 
 of sand and gravel can be obtained. Fortunately, the 
 favorable portions of many streams occur in flat-lying 
 areas near population centers, as for example, the Kern 
 River near iiakersfield, the Sisquoc River near Santa 
 Maria, and the Santa Clara River near Ventiu-a. 
 
 Floodplain Deposits. True floodplain deposits con- 
 sist of material deposited on plains bordering streams 
 bv periodic overflow of the streams from their chan- 
 nels. The sediments lieposited are normally composed 
 of silt and sand grains. However, these fine materials

 may mantle usable deposits of sand and gravel, par- 
 ticularly in areas where, in the geologic past, the 
 streams were more competent and transported greater 
 volumes of coarser material. The sand and gravel in 
 these older, deeper fioodplain deposits is similar to 
 that in channel deposits, and is suitable for use after 
 overlying fioodplain silt layers are removed. Flood- 
 plain deposits are best exemplified in the eastern por- 
 tion of the San Joaquin A'alley. 
 
 Terrace Deposits. Stream terrace deposits are 
 benchlike deposits of sand and gravel which border 
 a stream but lie above the level of the present flood- 
 plain. 
 
 These deposits are remnants of older fioodplains 
 through which the stream has cut. Terrace deposits, 
 because they are above the stream level, may be more 
 desirable than stream channel deposits if water tables 
 are shallow and abundant ground water makes stream 
 channel operations difficult. However, there is no 
 possibility of replenishment. The materials in these de- 
 posits have the general properties of stream channel 
 materials, but weathering processes may have dimin- 
 ished the quality of some of their constituents by 
 converting certain minerals to clay. The terraces along 
 the Kern River in the San Joaquin \"alley have been 
 a source of production for many years (Goldman and 
 Klein, 1961). 
 
 Alluvial Fans. An alluvial fan is a gently sloping 
 fan-shaped mass of loose rock material deposited at 
 the mouth of a canyon where a stream leaves the 
 mountains and enters an adjacent valley or plain. The 
 abrupt fiattening of gradient causes deposition of the 
 bulk of the bed load in a crudely stratified mass. 
 The cobbles and boulders are deposited at the apex of 
 the fan and the average particle size decreases toward 
 the sides and base of the fan. Fan deposits, because 
 of the frequent shifting of the stream channel, ordi- 
 narily contain lenticular beds or tongues of poorly 
 sorted sand and gravel interbedded with varying pro- 
 portions of silt and clay. The particles are subangular 
 to angular in the fans built by streams with small 
 drainage areas. The particles in large fans, covering 
 several square miles, are generally subangular to sub- 
 rounded. Suitable aggregate is obtained from alluvial 
 fans which are free from thick clay lenses. 
 
 The major sources of aggregate for the Los Angeles 
 area are the alluvial fans of Big Tujunga River in the 
 San Fernando \^illey and the San Gabriel River near 
 Azusa. 
 
 Beach Deposits. Sand and gravel formed by the 
 winnowing action of currents and waves on a beach 
 make exxellent aggregate. The gravel and coarse sand 
 size particles are generally well-rounded, hard, and

 been too complete. This close-up of

 the Bokersfleld area, shows the 
 
 effects of slight to moderote 
 
 weathering. The fracture in the 
 
 three-inch pebble in the center of

 of weathering.

 Photo 4. One method of obtaining a blend of material from alluvial fans is by drawing a scarifier 
 across the face of the pit. The loosened sand and gravel is then removed by an electric shovel which loads 
 a feeder-hopper for initial crushing.

 firm. The sands are commonly composed predomi- 
 nantly of resistant quartz and feldspar. Most beach 
 deposits, however, are thin, lack proper size gradation, 
 or are too inaccessible to be utilized for aggregate. 
 
 .\n ancient shoreline deposit of the Salton Sea is a 
 source of sand and gravel in Imperial County. The 
 deposit is composed of crudely stratified thin beds of 
 sub-rounded gravel and sand. 
 
 Older Geolof^ic Formations. Older geologic forma- 
 tions, particularly those containing partially consoli- 
 dated beds of sandstone and conglomerate, afford 
 usable sources of sand and gravel when post-dcposi- 
 tional weathering has not been too advanced. Ordinar- 
 ily, these formations have been subjected to long 
 periods of weathering and are too well cemented or 
 contain too much clayey material to be processed 
 
 economically at the present time. Accessibility, depth 
 of overburden, caliche coatings, and cemented layers 
 also present problems. However, considerable produc- 
 tion is obtained from the Poway Conglomerate of 
 Eocene age near San Diego, the Kern River Formation 
 of Pliocene age near Bakersfield (Goldman and Klein, 
 1961), and the Saugus Formation of Pliocene age near 
 Moorpark. 
 
 iModern beneficiating techniques can be used suc- 
 cessfully to obtain high quality aggregate from these 
 older formations.

 geologic formations as a source of concrete aggregate 
 and bencficiation techniques, was published in Rock 
 Products (Goldman, 1962).

 ECONOMIC DEVELOPMENT 
 
 Production. In 1966, approximately 66 million tons 
 of sand and gravel valued at about 74 million dollars 
 was produced from deposits in the counties covered 
 by this report. This represents approximately 55 per- 
 cent of the total production of sand and gravel in 
 California for that year. 
 
 The present market for sand and gravel in southern 
 California is primarily in residential, commercial, and 
 industrial construction. About 90 percent of the sand 
 and gravel is processed in fixed plants and sold com- 
 mercially. The remainder is produced by contractors 
 with portable plants for use by city, county, state or 
 federal agencies on public works projects. 
 
 Nearly all production is obtained from well-estab- 
 lished aggregate-producing areas located near popula- 
 tion centers. Few deposits are being developed an- 
 nually, and there is small possibility of locating a 
 large, as yet unknown, source close to a marketing 
 area. 
 
 The press of urban growth is being felt by pro- 
 ducers in southern California, and expansion of exist- 
 ing pits becomes increasingly difficult in view of 
 tightening zoning restrictions. In some counties, it is 
 virtually impossible to obtain a permit to open a new 
 pit. Future production will come from existing sources. 
 
 leading to depletion of a number of deposits within 
 the next 20 years. It may then become necessary to 
 import sand and gravel from deposits which are be- 
 yond the present economic limit of hauling (about 
 50 miles) in California (Goldman, 1959). 
 
 Mining Methods. Various methods of excavating 
 sand and gravel are used in southern California. The 
 most common method is to use a dragline, or electric 
 shovel. 
 
 End-dump trucks, scrapers and bottom-dumps are 
 used to haul material from the pit to the plant, al- 
 though many operators use conveyor belts for this 
 purpose. 
 
 The method of excavation for each commercial op- 
 eration is described in the tabulation of deposits. 
 
 Flant Processing. Commercial operations are lo- 
 cated on portions of deposits where the proper blend 
 of sizes of sand and gravel can be obtained in order 
 to produce a variety of products. Non-commercial 
 production by highway contractors generally is ob- 
 tained from portions of deposits where there is an 
 abundance of plus 1 1/ inch gravel to provide crushed 
 materials for use as road base or bituminous aggregate. 
 Ideally, a commercial deposit would contain about 
 60 percent gravel and 40 percent sand (minus "4 inch); 
 enough plus 1 '/z inch gravel to crush for use as road 
 base or bituminous aggregate; and sand in the correct

 in processing. This plant uses a heavy medio process by which the soft, lighter, unsound 
 
 porticles are floated off while the hard, dense, sound particles sink.

 Photo 7. The tremendous demand for sand and gravel to keep pace with the 
 growth in southern California has been met by producers who have built 
 high capacity plants. This new plant of the Consolidated Rock Products Company 
 near Irwindale is designed to attain ultimately a capacity of 3,000 tons 
 per hour. Photo courtesy Consolidated Rock Products Company.

 sizes and proportions for use in concrete. Few de- 
 posits meet these requirements, and plants are designed 
 to cope with natural deficiencies. 
 
 The plants in southern California range in capacity 
 from 30 to 1000 tons per hour; the average plant has 
 a capacity of 200 to .300 tons per hour. These are 
 medium-size plants. Larger plants with capacities up 
 to 1000 tons per hour furnish the aggregate for the 
 Los Angeles area. 
 
 Most plants are departmentalized to produce differ- 
 ent products. There is usually a "dry" side, where pit 
 run material is screened and crushed for use as road 
 base (or in some instances as bituminous aggregate) 
 and a "wet" side where sand and gravel is washed and 
 screened for use as concrete aggregate. Various stages 
 of crushing are used to reduce the gravel fraction to 
 the necessary sizes. Ordinarily a jaw crusher is used 
 for primary reduction, particularly where boulders 
 over 3 inches are present. Gyratory and rolls crushers 
 
 further reduce the gravel to minus 1 inch, and minus 
 % inch. Rod mills are used to manufacture sand from 
 !4 to Ys inch "pea" gravel to supplement natural sand 
 that is deficient in fine sizes. 
 
 The sand fraction ordinarily is washed and classi- 
 fied in spiral classifiers (sand screws). Plants process- 
 ing sand deficient in fine sizes usually employ wet 
 cyclone-type separators to recover fine sand which 
 may be present in the overflow from a classifier. In a 
 number of plants, hydraulic settling tanks are used to 
 separate the sand into various sizes. The desired blend 
 of sand sizes is drawn off tiirough gates in the bottom 
 of the tank and dewatered in spiral classifiers. 
 
 Plants processing clayey material use revolving 
 scrubbers or log washers to clean the pit run material 
 before further processing. 
 
 Standard screens which arc mechanically \ibrated 
 separate the gravel into the necessary sizes. 
 
 Some plants bcneficiate their raw material by re-

 moving soft shale in a heavy media separation which 
 utilizes the "sink-float" principle. The desired material 
 sinks and undesirable lighter fraction is floated off. 
 The heavy liquid is made up of a mixture of finely 
 ground magnetite and ferrosilicon with a range in 
 specific gravity that can be varied from 1.0 to 3.4. 
 The shale particles have a specific gravity of less than 
 2.3 and are easily floated off. Jigs also are used to re- 
 move light particles in the granule size range (Gold- 
 man, 1962, p. 68). These plants are located on the 
 Sisquoc River in Santa Barbara County, and the Santa 
 Clara River in Ventura County. 
 
 Almost all the commercial plants produce concrete 
 aggregate; about a fourth also produce bituminous 
 aggregate; all are capable of producing road base. 
 
 PRESENTATION OF DATA 
 
 Data on the individual deposits are presented in 
 the following tabulation and include name and loca- 
 tion and geologic description of deposit, fixed plant 
 description, and laboratory test data. The tabulation 
 is keyed to the accompanying map (plate 1) by being 
 arranged alphabetically according to the name of the 
 deposit, which in most instances is the related stream. 
 Where the deposit is in a formation not related to a 
 modem stream drainage, the formation name serves 
 as the deposit name. An alphabetical cross index of 
 operator-to-deposit is included at the end of the tabu- 
 lation. Also included is a comprehensive list of sand 
 and gravel producers in southern California for 1966, 
 arranged by county. This latter list contains, in addi- 
 tion to the operators described in this report, the 
 names and addresses of producers who intermittently 
 operate portable plants at various locations, or who 
 sell pit run unprocessed material. 
 
 The locations and extent of the deposits which were 
 visited and the fixed plants are shown on plate 1. The 
 deposits were plotted originally in 1:24,000 topo- 
 graphic maps and later reduced to the scale of the ac- 
 companying map. To show the deposits on this re- 
 duced scale, it was necessary to exaggerate the widths 
 of the deposits. The dimensions are given in the tabu- 
 lation under the column headed "Type and Extent". 
 
 Only the portions of old geologic formations that 
 have been commercially developed have been shown 
 on the map. For the arcal distribution of these forma- 
 tions, the reader is referred to the Geologic Map of 
 California and to geologic reports referred to in Divi- 
 sion of Mines and Geology Special Reports 52 and 
 52-A, Index to Geologic Maps of California. 
 
 The data for the classification of rock tvpes were 
 obtained by petrographic examination of approxi- 
 mately 200 pebbles in the % to 1 Vi inch range (a 
 size most useful for petrographic study and one of 
 commercial interest) from each deposit. In practice, 
 the 200 pebble sample amounts to all the Y^ to VA 
 inch pebbles in a pit run sample of about 100 pounds. 
 
 It has been found in other studies (Goldman and 
 Klein, 1961, p. 14) that for the ordinary stream de- 
 posit, examination of the size sample indicated above 
 is sufficient to establish the essential physical and 
 chemical character of the materials in the deposit. 
 Attention can be focused upon those rocks or minerals 
 that might have a deterimental effect on the concrete- 
 making qualities of the aggregate in which they are 
 included. 
 
 The rock type classifications which are followed 
 by the letters "USER" were obtained from unpub- 
 lished reports made by .Mr. Ira E. Klein for the U.S. 
 Bureau of Reclamation. 
 
 The laboratory test data were obtained from the 
 files of the Material and Research Laboratory of the 
 California Division of Highways in Sacramento. In 
 using these test results it should be borne in mind 
 that these tests represent only the samples submitted 
 and do not represent all the material in a given deposit. 
 An attempt \\as made to use only test results ob- 
 tained in the 5-year interval 1960 to 1965. When de- 
 posits were not tested recently, test results older than 
 1960 were used solely for the sake of completeness 
 and as a guide for future use. The dates of testing 
 are shown in the tabulation.

 Santa Ana River. 
 Proportion of 
 gravel to sand 
 decrease, from 
 70% (near con-

 Stream bed de- 
 posit extends up- 
 stream from the 
 confluenceof the 
 creek with the 
 Santa Ana 
 River, for about 
 12 miles. The 
 tributary Cajon 
 Creek also con- 
 tains sand and 
 gravel in the 
 stream bed for 
 about 10 miles 
 upstream from 
 it. junction with 
 Lytle Creek. The 
 deposit on Lytle 
 Creek ranges 
 from 1000 to 
 2000' in width; 
 and from 70' in 
 depth upstream, 
 to 20' in depth 
 near the Santa 
 Ana River.

 The gravels are 
 hard and round;
