Hiltgen, and others PURPOSE AND SCOPE OF THE WORK AND REPORT Tbe data presented In this report were collected by the U.S. Geological Survey as a phase of the investigation of ground-water geology and hydrology of the Edwards Air Force Base area. The study was made in cooperation with the Department of the Air Force but also was coincident with the U.S. Geological Survey investigation of water wells and general hydrologic conditions throughout much of the desert region of southern California. The overall study of general hydrologic conditions in the desert is part of a cooperative program with the California Department of Water Resources. The desert regions of California are characteristically regions of nearly barren mountain ranges and Isolated hills surrounding broad valleys which are underlain by alluvial deposits derived from the surrounding hlgnlands. The valley areas generally contain gr'-una water that has a wide range of chemical quality, but much of the water can be develnped for beneficial use. The general objective of the cooperative investigation was to collect and tabulate hydrologlc data for the Edwards Air Force Base and surrounding area in order to provide the military, public agencies, and the general public with data for use in planning water-utilization and development works, and for use in the overall ground -water investi- gation of the area. Accordingly, the scope of the work carried out by the Geological Sui-vey has included: (l) Visiting and examining all the water wells within the limits of Edwards Air Force Base and visiting and examining selected wells in the area bordering the base on the south and southwest, determining and recording the locations of wells In relation zo geographic and cultural features and the public-land net, and recording well depths and sizes, types and capacities of pumping equipment, uses of the water, and other pertinent information available at the well site; (2) measure- ments of the depth to the water surface below an established and described measuring point at or near tne land surface; (3) selection of representative wells to be measured periodically In order to detect and record changes of water levels; and (U) collection and tabulation of well records, including well logs, water-level measurements, and chemical analyses. The work has been done by the Geological Survey, under the general Bupervision of H. D, Wilson, Jr., district engineer In charge of ground- water Investigationa in California, and under the airecticn of Fred Kunkel, geologist in charge of the Long Beach subdistrict office. LOCATION AND GEIffiRAL FEATURES OF THE AREA The Edwards Air Force Base area described In this report (fig- l) covers approximately 880 square miles in the north-central and north- ecstem parts of Antelope Valley. Tl-.e principal connnunities in the area are Lancaster, Rosamond, and "awards Air Force Base. The area is in the sout.'-.westem part of the Mojave Desert region between long 117*30' and ll8*17' W. and lat 3U'U0* and 35' N. 'Die area described in this report is bordered by the following areas described in previous reports of the Geological Survey: To the west and northwest, the Willow Springs, Gloster, and Chaffee area (Kunkel and Dutcher, I960); to the north, the Fremont Valley area (Dutcher, 1959); to the east, the west pert of the Middle Mojave Valley area (Page, Moyle, and Dutcher, 1959); ane6 of the Tehachapi hkjuntains. Tne drainage of the area is closed, and the infrequent runoff flows toward the playa lakes in the lowest parts of the valley. The Kramer Hills are the dominant topographic foms in the eastern part of the area. The Rosamond and Bissell Hills rise above the alluvial plain near Rosamond in the west and north-central parts of the area. The hills consist mainly of igneous rocks, which yield little water. PREVIOUS WORK AND ACKNOWLEDGMENTS Data on ground water In the Edwards Air Force Base area are contained in several U.S. Geological Survey water-supply pepers and in reports by the California Departaent of Water Resources and California Dei)artment of Public Works, Division of Water Resoui-ces (table 3). ■Rie California Department of Water Resources and the Los Angeles County Flood Control District supplied pertinent open-file information. The Corps of Engineers, U.S. Army, also supplied water-level records and other miscellaneous data. The data contained in a private report J nace aveixaaie by Mr. Cyril Williams contriDutea greatly to the ccopleteness of the data in the northwest part of the area. The geology, as shown on figure 2, is generalized after published aapping by T. W. Dibblee, U.S. Geological Suivey, in the Alpine Butte, Boron, Castl-i Butte, Kramer, aoid Rogers Lake quadrangles, unpublished mapping by L. C. Dutcher, and unpublished mapping by ffr. Dibblee in the Rosamond and Willow Springs quadran^es. Tte cooperavioa and assistance by the agencies and individuals listed above is gratefully acknowledged as is the assistance given by the many ranchers, well owners, drillers, and others who contributed aoterially to the completeness of the data presented in this report.

Hie consolidated rocks include igneous intrusive and metamorphic rocks of pre-Tertiary age and continental volceuiic and sedimentary rocks of Tertiary age. The igneous and metamorphic rocks of pre-Tertiary age are for the most part impervious and, except for minor amounts of water from cracks and weathered zones, yield little or no water. Tne consolidated rocks of Tertiary age consist of basalt, felsic volcanic rocks, and nonmarine sedimentary rocks. Dibblee (196O, pi. 8, 195021^ and 1958b), included all these rocks in the Tropico group of Mioceae('') to Pllocene(?) age. "hie sedimentary rocks include conglomerate, sandstone, siltstone, shale, limestone, and water-laid tuff and agglomerate. For the most part the consolidated sedimentary rocks are poorly permeable, but if penetrated by wells probably would yield small amounts of water in some places. The felsic volcanic rocks include the Bobtail quartz latite member of the Oen Hill formation of Miocene(?) age mapped by Dibblee in the Wl^^v^w .yyi\^..^,., .i..^ Rosamond quadrangles, and otlier volcanic rocks of ' Itic, dacitic, and rhyolitic composition. Bxtrueive and intrusive basalt of Miocene(?) to Pliocene age also occuis in the area. Altnough the basalts are poorly permeable, if penetrated by wells part of the extrusive basalts probably would yield small to moderate amounts of water locally. The unconsolidated deposits include older alluvium and older fan deposits of Pleistocene age, old windblown sand of Pleistocene and Recent age, and younger alluvium, younger fan deposits, playa euid lakeshore deposits, and active dune sand of Recent age. The older alluvium of late Pleistocene age, consists of con5)act arkosic gravel, sand, silt, and clay. The deposits are weathered, and locally the feldspar has been altered to clay. Beneath the valley areas the unit is finer grained and better sorted than near the hills where it is predominantly gravel. The thickness of the older alluvium varies greatly from place to place because it overlies an erosional surface of considerable local relief. Where saturated, the older alluviun yields large quantities of water to wells. The older fan deposits, of Pleistocene age, consist of slightly consolidated fanglooerate or unsorted, unbedded boulder gravel, cobble-pebble gravel, and sand occurring as isolated erosional rejanants. The materials are mainly from a granitic source, but fragments of basalt, andeslte, dacite, and metamorphic rocks are cocnon. Ihe xmlt is nearly everywhere unsaturated; however, its attitude suggests that locally it may extend beoeatb the younger deposit* and, where saturated, may yield soall quantities of water to deep wells. 10 The old vindblown sand is mostly stabilized, unconsolidated to partly indurated, and generally fine grained or very fine grained. It is above the water table, but in sone places it contains small quantities of perched ground water. The yo-onger alluvium, of Recent age, consists of gravel, sand, silt, and clay. The deposits are unweathered and near the hills the unit consists predominantly of poorly sorted gravel and sand, but beneath the valley areas it is finer grained and better sorted. The thickness of the younger alluvium is not generally known but presumably is nowhere greater than about 100 feet. Where saturated in the lower parts of the valleys, the younger alluvium yields moderate quantities of water to wells. The yotmger fan deposits, of Recent age, are mostly poorly sorted bculders, erkosic gravel, sand, silt, euid clay derived fi-om nearby hills or mountains. The materials have been transported only a short distance and mainly represent mudflow or slope-wash debris. Near the hills "t' '^ci^ntalns the younger fan deposits are coarse grained, but they become finer with increasing distance frco the areas of active exosion. These deposits are poorly sorted aid poorly permeable, are usually above the water table^ and are unproraisini"; as sources of water. In the lower parts of the valleys, tne ailuviui oepcsics arc over- lain by playa deposits, younger and older dune sand, and lakeshore Its. The playfi deposits are mainly clay and silt of low permeability and tije rcjat'...^.^, units are generally above the water table and are of little or fiO Importance with regard to grr^und water in the erea. U In 1959 the water levels In wells ranged from near land surface beneath the lowest parts of the valley areas to more than 280 feet below the surface of the higher parts of the alluvial fans and plains. Ground-water rec arge to the area is from subsurface flow from adjoining areas, from infiltration of rain, end from percolation of infrequent runoff in streams that cross the fans to the playas. 12 DESCRIPTION OF TABLES The tables in this report contain or refer to all known data, published or unpublished, for wells located on Edwards Air Force Base and all kiiown data, published or unpublished, for selected wells in the area surrounding the base. In table 1, all wells canvassed in the Edwards Air Force Base area for which data are available are listed in numerical order. In table 2, cross indexes are given for numbers previously assigned to wells by others and well numbers assigned by the Geological Survey. In table 3j publications or reports which contain water-level measurements made in wells in \.he Edwards Air Force Base area are given . In table k, the wells are listed for which periodic water-level measurements are available. Table 5 contains all available unpublished records of water levels in wells and the measurements made by the Geological Survey through March I96O. Table 6 contains logs of wells, and table 7 contains chemical i.yses of waters from wells. 13 t^LL-NUMBEFING SYSTEM The well-nuobertng system used la the Edwarde Air Force Base area conforms >,o that used in vlj-tually all ground-water Investigations made by the Geological Survey in California since 19'»0. The system has been adopted by the California Department of Water Resources and by the California Water Pollution Control Board for use throughout the state. Wells are assigned numbers according to their location in the rectangular system for the subdivision of public land. For example, in the number 8/11-35J2 the part of the number preceding the slash indicates the township (T. 8 N.)* the part between the slash and the hyphen indicates the range (R. U W. ), the number between the hyphen and the letter Indicates the section (sec. 35), and the letter Indicates the UO-acre subdivision of the section as shown in the accompanying diagram. D E c B A F G H M L K J U P Q R Within the UO-acre tract, the wells are numbered serially as indicated by the ftn*l digit. 'Rius, well 8/11-35J2 is the second veil tn be lUted In tlic MEiSB^ see. 35, T. 8 N. . R. 11 W. (San .-.-.. ino Dcse ani meridian). Ik Because all the wells In the Edwards Air Force Base area are in the northwest quadrant of the San Bernardino base and meridian lines, the foregoing abbreviations of the to%ra3hip and range are eufficient. For well numbers where the letter Z has been substituted for the letter designating the UO-acre tract, the Z indicates tnat the well is plotted from unverified location descrlptionsj the indicated sites of such wells were visited but no evidence of a well co'old be found. Prior to the work done by the Geological Survey in the Edwards Air Force Base area, the Los Angeles County Flood Control District numbered wells on the basis of an arbitrary grid network. To correlate data identified by this older numbering system a supplementary cross index is shown in table 2 in which wells are listed in order according t") the Flood Control District numbers. 15 RBFBRENCE3 CITED Badei-,, J. 3., Page, R.

Altitudes given are in feet above mean sea level for the land- surface datum at the well. Land-surface datum is a plane of reference which approxioates land surface. Altitudes given in whole feet ai-e interpolated from topographic maps. Altitudes given in feet and tenths were determined by spirit leveling (from Corps of Engineers, U.S. Army, records or by Cyril Williams, Jr., engineer). Measurenents . .-iost of the water-level measurements were made by the U.5. Geological Survey; a few were made by the Corps of Engineers, U.S. Army, in 191^ or by Cyril Williams, Jr., engineer, in I929 and I93O. All measurements of water level have been adjusted to depth below land- surface datum. That is, the altitudes of the measuring points as reported above or below land-surface datum have been subtracted frcm or added to the water-level measurements. Depth of well . Depths given in whole feet are reported depths; depths given in feet and tenths were measured by the Geological Survey at the time of the field canvass. 7/9-I7NI. y. H. Brown. Depth 32U ft.
