Moyle, Jr. PURPOSE /JWD SCOPE OF THE iiORK AW PvEPORT The data presented in this report \rere collected "by the U.S. Geological Survey as a phase of its investigation of vater veils and general hydrologic conditions throughout rauch of the desert region of southern California. This study was made in cooperation vith the U.S. Noval Ordnance Test Station at China Lake, Calif., and with the California Department of ;/ater Resources. The general objective of the cooperative investigation is to collect and tabulate all available hydrologic data for the desert basins in order to provide public agencies and the general public \rith data for use in planning water utilization and development \TOTk and for use in subsequent ground-water investigations. Accordingly, the scope of the \Torli carried out by the Geological Survey in each area has included: (l) Visiting and examining most of the i^ater rrells in the area_, determining and recording their locations in relation to geographic and cultural features and the public-land net, and recording well depths and sizes, typeG and capacities of punping equipment, uses of the water, and other pertinent information; (2) measurements of the depth to the water surface below an established and described measuring point at or near the land surface; (3) selection of representative wells to be measured periodically in order to detect and record changes of water levels; and (^4-) collection and tabulation of well records, including well logs, water-level measui-ements, and chemicu.1 analyses. The work has been carried on by the U.S. Department of the Interior, Geological Survey, under the general supervision of H. D. Uilson, Jr., district engineer in charge of ground-water investigations in California, and under the direction of Fred Kunliel, geologist in charge of the Long Beach subdistrict office. The field- work was carried on and described by the authors of the following reports: Fred Kimlcel, G. H. Cliase, and U, J. Hiltgen (195^); ^^^ \1, R. Moyle, Jr., and Fred Kuniiel (1960). In addition, unpublished data from fieldwork done by M. A. Pistrang ere included. LOCATION AND GENEPAL FEATURES OF TIIE APxEA Tlie Indian iJells Vcilley area, as described in this report (fig. l), covers approximately 1^500 square miles and in general includes parts of the Sierra Nevada, Coso Range, El Paso Mou^itains, Spangler Hills, and Argus Range. The principal communities in the area are China Lake, Ridgecrest, Inyokern, Little Lake, and Searles. The area is in the northern part of tlie Ilojave Desert region tet\^^een lat 3;5'*15' and 36**00' N. and long 117^25' and llS'*15'¥. Tne southern boundary coincides with the northern "boundary of the Fremont Valley area after L. C. Dutcher (1959) • Tl^e -^restern boundary lies along the crest of the Sierra Nevada. 'Ihe northern boujidary coincides ■'.rith the northern edge of the Little Lake cand iiountain Springs quadrangles, The eastern boundary is approximately the crest of the Argus Range. The area is shoim on all or parts of the following U.S. Geological Survey topographic quandrangle maps at a scale of 1:62,500: Little Lake, Moujitain Springs, Onyx, Ridgecrest, Inyokern, Searles Lake, Randsburg, Cross Iiountain, and Saltdale; and the Trona sheet at a scale of 1:250,000. Access to the area is provided by U.S. Higlivays 395 sind 6 and numerous oth.er paved and unpo.ved roads. Geographically, the arer. is one of Interior drainage uith no perennial streams. The principal landforms are 'broad alluvial fans and alluvial plains "built out from the surrounding moujitains. In general, the mountain areas are composed of grcnitic, metamorphic, sedimentary, :::ac\ volcanic rocks irhich are of little importance with respect to the yield of vatcr to irells in these areas, except insofar as they ujiderlie a large part of the catchment area of the watershed. Broad allvaal fans and alluvial plains extend into the area from the northern slopes of the 31 Pa.so Kountains, the eastern slopes of the Sierra Nevada, the southern slopes of tlie Coso Range, and the western slopes of the Argus Range. The Ic^/est parts of the area are occupied "by playa lakes irhich usually are dry, except during and after infrequent periods of heavy precipitation. PRSVIOUS ".'ORK MD ACM0"7LEDGI^L1TS Data on ground water in Indian '.Tells Valley area are contained in reports by C. H. Lee (1913 ); J. T. V-histler (1925)^ D» G. Thompson (1929), "vilcox, Hatcher, and Blair (l95l)^ and Kunl^el, Cliase, and Kiltgen (195^)- The geology sho^m on figure 2 is "by v.-. R. Moyle^ Jr., and is generalized largely after published mapping of the Saltdale quadrangle by T. W. Dibblee, Jr. (1952); after unpublished mapping by T. H, Dibblee, Jr., for the Randsburg, Inyokern, and Cross Mountain quadrangles; after unpublished mapping by Fred Kunlcel and G» H. Chase for the Inyokern, Ridgecrest, Mountain Springs C?.nyon, and Little Lake quadrangles; and after unpublished mapping by Roland E. von Huene for the mountainous areas on the Mountain Springs Canyon and Ridgecrest quadrangles. The cooperation and assistance given by the many ranchers, veil owners, djrillers, and public agencies contributed materially to the completeness of this report and are most gratefully aclinowledged. 8 GEOLCGIC AND HYDROLOGIC FK\TURj33 OF THE ARM The geologic units in Indian ','ells Valley area can "be grouped into t^ro bror.ci c£.tegories (fig. 2). They are^ first, the crystalline rocks of the o8.senient complex and, second, the sedimentary and volcanic rocks. The basement complex includes undifferentiated plutonic, hypabyssal, and metp.morphic rocks of pre-Tertiary age. For the most part, the basement- complex rocki rre impervious end., except for miner amounts of vater in fractures or vea-thered zones, yield little or no vater to wells . The volcanic rocks include basalt, tuff, pumice, andesite, rhyolite, and dacite of Tertiary and (quaternary age that occur in the mountains to the north, east, and south of Indian Wells Valley. Like the rocks of the basement complex, the volcanic rocks are impervious and yield little •^•ra.ter to wells. The sedimentary rocks include alluvium, fan deposits, lake deposits, windblo-vm sand, and landslide debris of Tertiary and Quaternary age. Some of the older more compacted formations of Tertiary age yield little water or water of poor quality, but some of the unconsolidated sedimentary deposits of Pleistocene age yield water readily and comprise the main water-bearing units in the area. The Goler Formation of Dibblee (1952), of Tertiary age, is highly compacted arkose, clay, shale, and conglomerate which yields very little water to wells. The Goler Formation generally is impervious and ground water travels along the contact between the Goler Formation and the younger sedimentary deposits above. The Ricardo Fonnation (bibblee^ 1952), of Tertiary age, consists of silt, sand, gravel, clay, limestone, opal-chert, congiumerslte, tuff, "basalt flovs, andesite breccia flovs, and granitic cobbles. In general, these rocks are poorly permeable and yield only small amounts of poor-quality irater to \Tells. ■ ' The basalt, of Tertiary age, in part overlies and in part intrudes the Ricardo Formation. This unit is not considered to be water bearing in the mapped area. The volcanic and sedimentary rocks of Tertiary age in the Lava Mountains include andesite, undifferentiated volcanic rocks, and sedimentary rocks. The andesite, of middle and(or) late Pliocene (.) age, is composed of extrusive masses of broTrn to red andesite porphyry. Tlie undifferentiated volcanic rocks, of middle and(or) late Pliocene(?) are, is composed of yellov-gray volcanic sandstone and conglomerate, white to tan tuff and tuff breccia, brown andesite breccia, and purple to broim andesite porphyry. The sedimentary rocks, of middle Pliocene age, are conrposed of white tuff and tuff -breccia, tan to red arkosic sandstone, conglomerate, siltstone, and tan rhyolitic f anglomerate . Old mine shafts dug to depths of several hundred feet in the volcanic rock yield very small amounts of water. These shafts have been used as wells. Small amounts of water are sometimes obtained from shallow dug wells that collect water from the interface between the hard sandstone or volcanic rocks and tiie overlying younger alluvial material. Tlie v/ater is of good quality. 10 The pumice cones, of Tertiary and Quaternary age, are composed of perlitic pumice and rhyolite vith some obsidian flows. This material is above the regional water table and yields virtually no water to wells. The Coso Formation (Schultz, 1937)^ of late Pliocene or early Pleistocene age, is predominantly beds of steeply dipping white pumice 1^ the mapped area; however, as described by Schultz (1937)^ the unit consists mainly of silt and sand with some gravel interbedded with the pumice. This formation is highly permeable but, as its position is above the regional water table, it probably does not contain large quantities of ground water. The older alluvium of Quaternary age is composed of unconsolidated weathered gravel, sand, silt, and clay, \7here saturated, the deposits yield water freely to wells. This material underlies parts of the younger alluvial deposits in Indian VJells Valley and is the principal source of ground water. South of Freeman Junction, the older alluvium probably is very thin, above the water table, and underlain by the Ricardo Formation at shallow depth. It does not appear to yield much water to wells in this area. 11 Tiie older fan deposits are subdivided into three units. Unit 1 of the older fan deposits is the oldest of the three units and is composed of "boulders, sand, and gravel that range from light yellow/ to light ■bro^ra in color. 'Yae early Pleistocene age of this unit is "based on forisils found "by T. '.1 , Dibblee, Jr. (oral communication, I96I). It is lithologically similar to the Coso Formation as described by Schultz (1937; P' oO), and its fossil fauna suggest that it is about the same age as the Coso Formation. Thus, it appears that this unit may be equivalent, at least in part, to the Coso Formation. These deposits have been brolien by the Garlock fault, imich has impeded the lateral movement of ground irater, raising the irater table on the upgre.dient side of the fault and causing a line of small springs, The amount of flow from these springs is very small, hovever. Unit 2 of the older fan deposits of Quaternary age is composed of boulders, sand, and gravel that is firmly cemented with calcareous cement. Tliese deposits are above the water table and are not water bearing. Tliis unit is approximately equivalent to units 1 and 2 of the old lacustrine deposits. Unit 3 of the older fan deposits of Quaternary age is composed of silt, sand, and gravel. This unit locally overlies the older alluvium and old lacustrine deposits and in most of tlie mapped area is a relatively thin unit. It is mostly above the water table and is probably not water bearing, except perhaps at the mouths of some mountain canyons. 12 Tiie olcT Ic-.custrina deposits of (^r.ternr.ry age are subdivided into ti:o units both of ^rhich are composed of silt, sand, clay, and fresh- water marl, cemented vith calcareous tufa cement. Tnese units are separated by an ancient shoreline of calcareous tui'a at an altitude of 2,200 feet above mean sea level. Tlie older loT^er unit (l) is also sepa.rated from the younger unit (2) by an angular unconformity. The lo'vrer older unit dips rather steeply in local areas (up to 25°) vhereas the upper younger unit irj relatively flat. Both units 1 and 2 of the old lacustrine deposits contain ground water below the regional water table, but the water is generally of poor quality. The old lalieshore deposits of 'Quaternary age (VJisconsin?) are composed of silt, sand, clay, and lime cement. Tliese deposits w-ere foxmed when water stood on the playa surface and now are above the water t-:'.ble. Tiie older dune- sand deposits of (Quaternary age are moderately consolidated. They are anchored in their present position by shallow ground water and vegetation. They yield little water to wells because of the small saturated thickness. The Black Mountain Basalt of Hulin (1925), of ^liuaternary age, is composed of vesicular to dense olivine basalt. Tliis fonnation crops out in the El Paso Mountains and is above the regional water ta.ble. The unnamed volcanic rocks of 'Quaternary age are composed of dark, vesicular to dense, e^ctrusive basalt flows. In general, they are above the regional water table and yield virtually no water to irells . 13 The yoimger alluvium of Recent age is unconsolidated, moderately to -^^ell- sorted sand, clay, and gravel, which has "been carried a moderate distance from the surrounding mountains that are the source area. In general, the younger alluvivM thinly covers some of the older deposits. These deposits are ahove the water table but, if saturated, would yield water freely to wells. The younger fan deposits of Recent age are unconsolidated, poorly to moderately sorted gravel, ss,nd, and silt, with some mudflox/ debris. They are derived from local highlands and deposited close to the source area. In general, these deposits are above the regional water table but, if saturated, they might yield small amovmts of water to wells. The plays, deposits of Recent age occur principally at the base level of drainage areas. They consist mainly of silt and clay and are of low permeability. IJater contained in these deposits usually has a moderate to very higli concentration of dissolved solids. The dune sand of Recent age is composed of windblown sand. Except where held by shallow ground, vrater or vegetation, the sand is actively drifting. The materials shoim on the geologic map as sand and interdune playa deposits of Recent age are the same as described under dune sand and playa deposits separately, earlier in the text, but because the playas are small, ranging from a few feet up to about 100 feet across, these tira units locally have been combined into one on figure 2. lit DESCRIPTION OF 'ji'"-.BL3G The tables in this report contain or refer to all knovn data, published and unpublished, for wells in the Indio-n ^,'ells Valley area . In table 1, all veils canvassed for which data are available are listed according to township, ran^e, and section. See we 11 -numbering systera. Table 2 lists all luiown ^r^.ter- level measurements,, published and unpublished. Table 3 lists all knoT-rn chemical analyses of water. Part A is for ground water. Part B is for surface water. Table ^!- contains all available drillers' logs of wells. Table 5 contains all available test data on crater wells. 15 HYDROGPAPHG OF IffiLLO Figures 3-^ s-^e liydrographs of wells in Indian '^/ells Valley compiled from continuous -^rater-level recorders. Circles on the graphs indicate measurements that were made by vetted steel tape. Vertical lines indicate the range hetiT'een the high and lo\r readings for the month taken from wa,ter-level recorder charts. Not all the measurements that were made by wetted tape appear on the hydrographs because some of them fall between the monthly high and low readings already on the hydrographs. For the complete records of the "s^etted tape measurements, see table 2. 16 :jsll-iiui'Deriiig cysteI'I Tlie veil-numbering system used in this report is that used "by the Geological Sui-vey in California since 19'i-0. It has been adopted by the California Department of !Jater Resources and by the Califomia IJater Pollution Control Board for use throughout the state. Uells are assigned niunbors according to their location in the rectangular system for the subdivision of public land. For example, in the number 26s/^OE-33P2, vhich iras assigned to a veil in Ridgecrost, the part of the number preceding the slash indicates the tovnship (T. 26 o.)^ the part bet^reen the slash and the hyphen is the range (R. kO 3.)^ "the number betveen the hyphen and the letter indicates the section (sec. 33), and the letter indica.tes the i-i-O-acre subdivision of the section as sho^m in the accompanying cUagram. D c 3 E TP G H hi L K J n P U R 17 Hitliin the ^-:-0-acrc tract_, wells are numbered serially as indicated "by the final digit. Thus, veil 263/^0E-33P2 is the second well to be listed in the SE-^b:/:^- sec. 33 • Because the area lies entirely in the southeast quadrant of the Mount Diablo base and meridian lines , the foregoing abbreviation of toimship and range numbers is sufficient. For parts of the valley vrhere the survey lines are incomplete or irrecoverable, the system of land sibdivision has been projected for reference purposes only. Exceptions to the system of numbering wells according to their position in the ^i-O-acre subd.ivision of the section are to be found. In these instances where the wells have been found to be located inaccurately, they have been correctly'- plotted on the map but the original nuiiiber assigned, has been retained. Tliis has been done to avoid confusion in the numbering system and to prevent the necessity for changes in repoits already published.. Fortunately, these mislocated wells are fevr in number and are seldom misplaced any farther than one of the adjoining 40-acre subdivisions. 18 REFERENCE 3 CIlED DiblDlee, T.
