  Description:
    Abstract: The U.S. Geological Survey (USGS) compiled a database of aggregate sites and geotechnical sample data for six counties - Ada, Boise, Canyon, Elmore, Gem, and Owyhee - in southwest Idaho as part of a series of studies in support of the Bureau of Land Management (BLM) planning process.  Emphasis is placed on sand and gravel sites in deposits of the Boise River, Snake River, and other fluvial systems and in Neogene lacustrine deposits.  Data were collected primarily from unpublished Idaho Transportation Department (ITD) records and BLM site descriptions, published Army Corps of Engineers (ACE) records, and USGS sampling data.  The results of this study provides important information needed by land-use planners and resource managers, particularly in the BLM, to anticipate and plan for demand and development of sand and gravel and other mineral material resources on public lands in response to the urban growth in southwestern Idaho.
    Purpose: These data were compiled to aid in the study of aggregate sources in the southwestern Idaho region. The digital geospatial database is one of many being created by the U.S. Geological Survey as an ongoing effort to provide geologic information for use in a geographic information system (GIS) and in spatial analysis.

  Data_Set_Credit: Surface ownership as listed in this database, is based on a Bureau of Land Management spatial database provided by Geographic Sciences at the BLM Idaho State Office, 1387 S. Vinnell Way, Boise, ID 83709 through a data sharing agreement (BLM Memorandum of Understanding ID-423).  The ownership data were compiled by BLM from December 2002 to October 2003 from Cadastral Survey data derived from the Geographic Coordinate Database (GCDB) and from land status data reported in the BLM Land and Mineral Records LR2000  system (http://www.blm.gov/lr2000/).  Polygons of surface ownership are identified as private, State of Idaho, BLM, Bureau of Indian Affairs, Bureau of Reclamation, U.S. Fish and Wildlife Service, U.S. Forest Service, or Military Reservations.  Sub-surface mineral rights management is not available in a digital format at this time.  For complete metadata or additional information, contact Nina Madry (208)373-3958 or Stephanie Singer (208)373-3961at the Bureau of Land Management.

      Process_Description:
        (1998 - 2000) Idaho Transportation Department source records were researched and compiled by Phillip Moyle, USGS, and Rikka Bothun, student. Other students from University of Arizona entered sample location information (containing spatial data) and geotechnical information into two separate Microsoft Excel tables. These two tables would later be "joined" together in a "many to one" operation in ArcView 3.2.

        (2002 - 2003) Phillip Moyle and John Wallis reviewed the preliminary spatial and geotechnical data tables, made revisions as necessary, and added additional qualitative and quantitative ITD data. Additional sample location and/or geotechnical data from Army Corps of Engineers (ACE), Bureau of Land Management (BLM), and the U.S. Geological Survey (USGS) were also added to the data set.
        In order to provide a dBASE4 file as the final product of this GIS, the following steps were used in the compilation process of the digital tabular data of this dataset. Two preliminary tables (spatial and geotechnical data) were compiled in Microsoft Excel. The spatial and geotechnical data tables were saved as Tab-delimited text files for easy import into ArcView 3.2. The spatial data were then "joined" to the geotechnical data in a "many to one" procedure using the Site_Id as the common field. A shapefile was created from the "joined" table producing a preliminary dBASE4 file. After some organizational changes, the final dBASE4 file was produced (of2004-1067.dbf).

        (2003) ArcView query was used to identify polygons (geologic units) that have point locations (material source sites) within them. This geologic coverage encompasses only a small portion of the study area and therefore not all material source sites are assigned a geologic unit name. Once identified, the geologic units were added to the database to provide additional qualitative information to each material source site located within a geologic polygon.

        (2003) ArcView query was used to identify polygons (land ownership) that have point locations (material source sites) within them. Once identified, the land ownership status types were added to the database (of2004-1067.dbf) to provide additional qualitative information to each material source site. Originally the land ownership coverage was larger than the study area. In order to eliminate unnecessary data, the land ownership was "clipped" to include only the 6 county study area of southwest Idaho.

        (2003) In ArcView 3.2 UTM coordinates were determined by correlating material source site township-range-section data with its associated UTM location on a Digital Raster Graphic (DRG). In ArcView the cursor was placed over the described location on the DRG and UTM coordinates were then annotated from the on-screen display into the database (of2004-1067.dbf). UTM coordinates are considered to be accurate to within 1320 feet (1/4 mile).

        (2003) Latitude and longitude were determined by importing a copy of the preliminary database into Arcview 3.2 and reprojecting it from UTM NAD 1927, zone 11 to decimal degree Geographic Coordinate System. Then ArcView script addxycoo.ave (ESRI) was run on the database to append decimal lat/lon coordinates to each material source site in the database. The lat/lon coordinates were then annotated into the database (of2004-1067.dbf).

        (2003) Road and river spatial data files for each of the 16 DLGs were merged into two (road and river) files. Next, each file was "clipped" to match the geographical extent of our six county study area that greatly reduced file size. The merged-clipped river and roads were used in ArcView map layouts.

      Attribute_Label: SITE_ID
      Attribute_Definition: Unique identification number assigned by U.S. Geological Survey (USGS) to identify the various material source sites.  Since most of the material source data were derived from Idaho Transportation Department (ITD) records, naming nomenclature for that agency was selected as the standard for their site records.  In the ITD system, the first two letters designate the county (OW = Owyhee, EL = Elmore, BO = Boise, GM = Gem, AD = Ada, CN =Canyon), and a 4-digit number designates the site, generally in chronological sequence.  For example, BO-0001 is a depleted ITD sand and gravel pit that first operated in 1935.  Material source site data from other agencies, for instance, the Army Corp of Engineers (ACE), Bureau of Land Management (BLM) or USGS, were each assigned an alphanumeric (county-number) sequence so long as it did not conflict with the established ITD system.  USGS sites were labeled with a two-letter county code followed by a number in the 5000 range, ACE sites were labeled with a two-letter county code followed by a number in the 6000 range, and Bureau of Land Management (BLM) sites were labeled with a two-letter county code followed by a number in the 7000 range.

      Attribute_Label: SITE_TYPE
      Attribute_Definition: Six types of sites were identified.  Two broad classifications - "sand & gravel" or "rock quarry" - were assigned by the compilers to reflect material of either alluvial origin (sand & gravel, lacustrine clay, etc.) or in-place rock (quarry rock).  Also recognized were four less common types of sites - "placer tailings," "mine waste rock," "cinder quarry," and "talus" - that did not fit easily into the two broad classifications.  Placer tailings, or dredge tailings, are alluvial materials that have been disturbed by mining in search of gold or other heavy metals, and mine waste rock is a product of surface or underground mining of in-place rock for valuable minerals or metals.  A question mark "?" follows the type of site name if the classification is uncertain.

      Attribute_Definition: The sand equivalent (SE) test, conducted according to AASHTO T-176 or ASTM D 2419 standards, measures the relative proportion of plastic fines and dust to sand size particles in granular soil and fine aggregate that pass the No. 4 sieve.  Sand equivalent expresses the concept that most granular soil and fine aggregate are mixtures of desirable coarse particles, cohesionless sand and dust, and generally undesirable plastic fines, so SE is a measure of the clay-like or plastic fines in granular soils and fine aggregate.  Through a series of steps to separate, disperse and then flocculate the sample, the SE score is determined as the ratio of the height of sand to the height of plastic fines reported as a percentage.

      Attribute_Label: LAWEAR_PCT
      Attribute_Definition: Formally named the Los Angeles Degradation Test and also called the LA abrasion or LA wear test, this procedure, conducted according to AASHTO T-96 or ASTM C 131 (fine) or D 535 (coarse) standards, measures the resistance of a coarse aggregate to degradation by abrasion and impact (Barksdale, 1991, p. 3-43).  A steel drum with a 5,000-gm pre-sieved and reconstituted sample and 6 to 12 steel balls is rotated 500 revolutions.  After the rotation and drying, the percent sample passing a No. 12 (1.70 mm, 0.077 in.) sieve is the Los Angeles Degradation value, sometimes termed the percent wear or percent loss.  Data ranges from lows of 10-17 for basalt and 13-21 for diabase to as high as 27-49 for granite and 33-57 for gneiss.  All LA Degradation Test data reported in the geotechnical analyses in the material source records were considered to be by the 500-revolution test method unless otherwise documented.

      Attribute_Definition: Aggregates are classified for various end uses based on ranges of their LA Degradation Test (percent wear) score: Class A = max 40; Class B = max 45; and Class C max = 50.  Several older (mid-1950s) geotechnical analyses in the ITD records report the LA Degradation class as "B non-Std." rather than merely the letter B.  No information was found to document the meaning (whether non-standard test protocol or results) of this term; however, it was entered into the database as shown in the laboratory report.

Resistance R values vary from 0 for water to approximately 100 for stiff, nearly rigid material; 80s and 90s for dense graded, high density crushed stone base course down to the 50s and 60s for less well graded and higher fines content gravelly materials.  R-Value is currently determined by the AASHTO T-190, or ASTM D-2844, test procedures.

      Attribute_Definition: Specific gravity of the size fraction greater than the No. 4 sieve (0.187 in).  CA is currently determined by the AASHTO T-85 or ASTM C 128 test procedures.  Specific gravity (SG) is the relative weight of an object (particle or aggregate sample) compared to the weight of an equal volume of water.  SG was reported in several different ways in geotechnical laboratory analyses in ITD and other agency records.  Four types are included in this database (see below):  1) SG Coarse Aggregate (CA); 2) SG Fine Aggregate (FA); 3) Bulk SG; and 4) SG of the + 3/4-inch fraction.  The various types of specific gravity were often poorly documented or entered into the geotechnical analyses reports, especially older ones, therefore, only clearly presented data were recorded in this data set.

  Overview_Description:
    Entity_and_Attribute_Overview: Due to data management concerns, this aggregate database (of2004-1067.dbf) was produced by compiling two data sets separately, one containing spatial (site description) information and the other containing geotechnical data from sample analyses. The spatial and geotechnical data tables were joined in Arcview 3.2 which produced the database "of2004-1067.dbf". The database includes an integrated body of data with 82 unique data fields.  The database includes 2882 entries containing information on 680 sites, as well as geotechnical sample data from 2,723 laboratory analyses collected from many, but not all, of the sites.  The 680 aggregate sites are divided into six classes:  sand & gravel (614); rock quarry (43); cinder quarry (8); placer tailings (8); talus (4); and mine waste rock (2).  Most importantly, the aggregate database (of2004-1067.dbf) includes detailed location information allowing individual sites to be located at least within a section and most often within a small parcel of a section.  Additional information includes, but is not limited to:  lithology-mineralogy or geologic formation (if known); surface ownership; size; production; permitting; agency; and number of samples.  Geotechnical data include:  lab number and test date; field parameters including sample location, type of material, and size; and the results of geotechnical analyses - gradation (grain size distribution), Los Angeles (LA) Degradation, sand equivalent, absorption, density, and several other tests.  About 95 percent of the 2,723 geotechnical sample records include gradation data, and 72 percent of the samples have sand equivalent data; however, LA Degradation, absorption, and bulk density data are only in about 30 percent of the sample records.
