Data on wells and test holes in this data set were used to identify elevations for the top of the Inyan Kara Group for the creation of a structure-contour map. This data set was created as part of the Black Hills Hydrology Study (BHHS). The BHHS is a long-term investigation that was initiated in 1990 as a cooperative effort between the U.S. Geological Survey (USGS), the South Dakota Department of Environment and Natural Resources (DENR), and the West Dakota Water Development District. West Dakota represents various local and county cooperators. The purpose of the study is to assess the quantity, quality, and distribution of surface and ground water in the Black Hills area of western South Dakota (Driscoll, 1992). The study area includes parts of Butte, Custer, Fall River, Lawrence, Meade, and Pennington counties in South Dakota. Process steps: Well construction, well location, and related data were retrieved from drilling records kept on file in the Rapid City, South Dakota, U.S. Geological Survey office. Wells were eliminated from the list if no geologic log was available. Values of latitude, longitude, and elevations of formation tops for wells were used as input to ARC/INFO to create a point coverage of these wells. Process date: 19990701 Revisions: revision 1.0 19990701 Reviews_Applied_to_Data: This electronic report was subjected to the same review standard that applies to all U.S. Geological Survey reports. Reviewers were asked to check the topological consistency, tolerances, attribute frequencies and statistics, projection, and geographic extent. The reviewers checked the metadata and a_readme.1st files for completeness and accuracy. Related_Spatial_and_Tabular_Data_Sets: Data for wells and test holes completed in the Minnekahta Limestone, Madison Limestone, Deadwood Formation, and the Minnelusa Formation (mnktswpt, mdsnswpt, ddwdswpt, mnlsswpt). As well as digital coverage of the top of the Inyan Kara Group (inkrscon) and surficial geology in the Black Hills Area (hydrogeo).

SunOS, 5.6, sun4u UNIX ARC/INFO version 8.0.1 U.S. Geological Survey 1999 map Hydrologic Investigations Atlas HA-744-A Rapid City, South Dakota U.S. Geological Survey none Altitude and location of wells were checked using 1:24,000 scale topographic maps published by the U.S. Geological Survey. Point features present. This data set includes wells and attribute information published in table 1 of U.S. Geological Survey Open-File Report 99-260. Points were plotted on mylar and checked for accuracy using 1:24,000 topographic maps. Latitude and Longitude for each well and test hole were taken from the USGS "Ground Water Site Inventory" (GWSI) data base. Initial latitude and longitude for each well site was obtained through location plotting on and interpolation from USGS 1:24,000-scale topographic maps, or from GPS locations taken in the field. 19980701 1.Latitude, Longitude, Site-id, and Owner information were downloaded from the GWSI database in a delimited ASCII text format. 2.The ASCII file was then imported into Microsoft Excel so that fields not present in the GWSI data base could be added. Information such as elevations of geologic formation tops, and hole depth were taken from well logs on-file at the U.S. Geological Survey office in Rapid City, South Dakota. 3.The Microsoft Excel file was then exported as a delimited text file so that a point coverage could be created in ARC/INFO. 4.The locations and attributes were verified. 19980701 First draft of metadata created by gjarrell using FGDCMETA.AML ver. 1.33 07/15/99 on ARC/INFO data set /home/student/gja/meta/stinkr_wells 20000313 Point Point 267 Universal Transverse Mercator 13 0.9996 -105.0 0.0000 500,000 0.0000 coordinate pair 18.18335 18.18335 Meters North American Datum of 1927 Clarke 1866 6378206.4 294.98 There is a point attribute table associated with this data. > >INKRSWPT.PAT: > >COLUMN ITEM NAME WIDTH OUTPUT TYPE N.DEC ALTERNATE NAME > 1 AREA 4 12 F 3 > 5 PERIMETER 4 12 F 3 > 9 INKRSWPT# 4 5 B - > 13 INKRSWPT-ID 4 5 B - > 17 SITEID 15 15 I - > 32 LOCAL 13 13 C - > 45 ALTITUDE 4 4 I - > 49 DEPTHINKR 5 5 I - > 54 ALTINKR 8 8 F 1 > 62 CHECK 3 3 C - > 65 INKR 8 8 I - > > AREA: Area of the point (assigned zero). PERIMETER: Perimeter of the point (assigned zero). INKRSWPT#: An ARC/INFO generated internal feature identity number. INKRSWPT-ID: User-assigned feature identity number. SITEID, LOCAL, ALTITUDE, and OWNER, were retrieved from the USGS Ground Water Site Inventory data base, all others were created by staff of the BHHS. Note: values of 9999 indicate no data. ------------------------------------------------------------------ SITEID: This is a unique number given to each well. SITEID is a combination of the latitude and longitude of the well, plus a sequence number for wells located at the same latitude and longitude. (Note: The latitudes or longitudes originally assigned to sites in GWSI occasionally are determined to be incorrect. In these cases, the latitude or longitude is corrected, but the station identification number generally remains unchanged. Thus, the latitude or longitude for an occasional site may not correspond exactly with the station identification number). LOCAL This is a unique number based on the Federal land-survey system for western South Dakota. LOCAL consists of the township number followed by "N" or "S" (north or south of the Black Hills Baseline), the range number followed by "E" or "W" (east or west of the Black Hills Meridian), and the section number, followed by a maximum of four uppercase letters that indicate, respectively, the 160-, 40-, 10-, and 2.5-acre tract in which the site is located. These letters are assigned in a counterclockwise direction beginning with the letter "A" for the northeast quarter. A serial number following the last letter is used to distinguish between wells located in the same 2.5-acre tract. ALTITUDE: This is the elevation of the well head above mean sea level, NGVD29. DEPTHINKR: The depth to the top of the Inyan Kara Group below land surface. ALTINKR: The elevation of the top of the Inyan Kara Group above mean sea level, NGVD29. CHECK: A single character denoting if the well had been site visited or not. A "U" denotes unchecked and a "C" denotes field checked. INKR: Value from ALTINKR rounded to nearest integer value. none U.S. Geological Survey Ask USGS - Water Webserver Team mailing
