Donation sent to the University of Idaho Library Government Documents Librarian a CD containing General Land Office maps on it. A readme file on the CD contains this information:"I obtained the attached GLO maps from Mitch Price at River Design Group who obtained them from another source. These maps apparently do not have a date, I assume it was stripped off when they were rectified. These maps show the Great Northern Rail line, it arrived in Bonners Ferry in 1892. The Spokane International Railroad (Union Pacific purchased this line) built a bridge across the Kootenai R. in 1906." "I am a bit puzzled on the map dates, the Kootenai River Master Plan indicated these maps are 1862-65 but they also show the Great Northern Rail line but not the Spokane International Railroad which seems to place them somewhere between 1892 - 1906 unless perhaps they were revised at a later date."Gary Barton USGS Tacoma, WA 253-552-1613 officegbarton@usgs.gov

The geology of the Rosalia 1:100,000 quadrangle, Washington and Idaho was compiled and published as a paper product by the Washington Division of Geology and Earth Resources (Waggoner, 1990). The U.S. Geological Survey converted the geologic data to a digital geographic information system (GIS) format as part of a larger effort to create regional digital geology for the Pacific Northwest. The digital geologic map database can be queried in many ways to produce a variety of derivative geologic maps.

Boundary describes the extent of the Spokane Valley-Rathdrum prairie aquifer from south end of lake Pend Oreille, Idaho - thru Rathdrum Prairie, the Spokane Valley, turning north to discharge at little Spokane River, and Spokane river north and west of the city of Spokane. Source data overview:Spokane Valley aquifer (WA State only) digitized in 1988 by Spokane Co. Engineer Dept from USGS 1977 hydrologic study of the Spokane Aquifer. This layer digitized from 1:24000 quad maps into the County's GDMS GIS. The USGS relied heavily on contour lines that described the valley floor to delineate the Spokane aquifer boundary. The original boundary had the Spokane River as it's west edge, but was revised (by Bea Leckaff Spokane County WQMP-GIS) in June, 1994, under the direction of Stan Miller to include the flood plain terraces on the west side of the river, down to the Little Spokane River confluence. The extent of the aquifer was revised again in March, 1995 to reflect new information from CH2MHill aquifer studies being done for the City of Spokane (to support Wellhead Protection). The revised aquifer extends the influence of impervious basalt outcroppings from the Spokane Falls area to the Trinity Triangle, (Drumheller Springs). The corrections were made by BBL from information provided by Stan Miller.

Idaho Portion of the Aquifer data came from Idaho Panhandle Public Health GIS SCALE: Idaho data digitized originally from 1:24000 USGS maps LAST UPDATED: March 1993- received Idaho data and matched to Spokane county aquifer data.

This data set maps and describes the geology of the Chewelah 30' X 60' quadrangle, Washington and Idaho. Created using Environmental Systems Research Institute's ARC/INFO software, the data base consists of the following items: (1) a map coverage containing geologic contacts and units, (2) a point coverage containing site-specific geologic structural data, (3) two coverages derived from 1:100,000 Digital Line Graphs (DLG); one of which represents topographic data, and the other, cultural data, (4) two line coverages that contain cross-section lines and unit-label leaders, respectively, and (5) attribute tables for geologic units (polygons), contacts (arcs), and site-specific data (points). In addition, the data set includes the following graphic and text products: (1) A PostScript graphic plot-file containing the geologic map, topography, cultural data, and two cross sections, and on a separate sheet, a Correlation of Map Units (CMU) diagram, an abbreviated Description of Map Units (DMU), modal diagrams for granitic rocks, an index map, a regional geologic and structure map, and a key for point and line symbols; (2) PDF files of the Readme text-file and expanded Description of Map Units (DMU), and (3) this metadata file. The geologic map database contains original U.S. Geological Survey data generated by detailed field observation and by interpretation of aerial photographs. The map was compiled from geologic maps of eight 1:48,000 15' quadrangle blocks, each of which was made by mosaicing and reducing the four constituent 7.5' quadrangles. These 15' quadrangle blocks were mapped chiefly at 1:24,000 scale, but the detail of the mapping was governed by the intention that it was to be compiled at 1:48,000 scale. The compilation at 1:100,000 scale entailed necessary simplification in some areas and combining of some geologic units. Overall, however, despite a greater than two times reduction in scale, most geologic detail found on the 1:48,000 maps is retained on the 1:100,000 map. Geologic contacts across boundaries of the eight constituent quadrangles required minor adjustments, but none significant at the final 1:100,000 scale. The geologic map was compiled on a base-stable cronoflex copy of the Chewelah 30' X 60' topographic base and then scribed. The scribe guide was used to make a 0.007 mil-thick blackline clear-film, which was scanned at 1200 DPI by Optronics Specialty Company, Northridge, California. This image was converted to vector and polygon GIS layers and minimally attributed by Optronics Specialty Company. Minor hand-digitized additions were made at the USGS. Lines, points, and polygons were subsequently edited at the USGS by using standard ARC/INFO commands. Digitizing and editing artifacts significant enough to display at a scale of 1:100,000 were corrected. Within the database, geologic contacts are represented as lines (arcs), geologic units as polygons, and site-specific data as points. Polygon, arc, and point attribute tables (.pat, .aat, and .pat, respectively) uniquely identify each geologic datum.

The digital geologic map of the Coeur d'Alene 1:100,000 quadrangle was compiled from preliminary digital datasets [Athol, Coeur d'Alene, Kellogg, Kingston, Lakeview, Lane, and Spirit Lake 15-minute quadrangles] prepared by the Idaho Geological Survey from A. B. Griggs (unpublished field maps), supplemented by Griggs (1973) and by digital data from Bookstrom and others (1999) and Derkey and others (1996). The digital geologic map database can be queried in many ways to produce a variety of derivative geologic maps.

The Spokane River flows westward into eastern Washington out of the northern end of Lake Coeur d'Alene in northern Idaho. The river and lake lie downstream of the Coeur d'Alene mining district, where over 56 million metric tonnes of metal-enriched tailings were disposed into the Coeur d'Alene River between 1886 and 1968 (Long, 1998). Geochemical analyses of riverine sediments in the Spokane River by the Washington Dept of Ecology (Johnson, 1999), the US Geological Survey (Grosbois and others, 2001; Box and others, in prep.) and an EPA contractor (URS Greiner, 2000, 2001) have indicated that Spokane River sediments are variably enriched in metals derived from those tailings. In this report we present a surficial geologic map (plates 1 through 8) of the unconsolidated deposits within and along the Spokane River in eastern Washington between the Idaho stateline and the confluence with Latah Creek about 20 miles downstream. Existing sample datasets for sediments and soils in and along the Spokane River are also located on the map and the surficial geologic unit that was sampled is noted. This work was undertaken in cooperation with the Washington Department of Ecology and the Environmental Protection Agency.

Rathdrum Comprehensive Aquifer Management Area Plan (CAMP) boundary of the Spokane Valley-Rathdrum Prairie Aquifer clipped at the Idaho border. Original boundary describes the extent of the Spokane Valley-Rathdrum Prairie aquifer from south end of lake Pend Oreille, Idaho - thru Rathdrum Prairie, the Spokane valley, turning north to discharge at little Spokane river, and Spokane river north and west of the city of Spokane. Spokane Valley aquifer (WA State only) was originally digitized in 1988 by Spokane Co. Engineer Dept from USGS 1977 hydrologic study of the Spokane Aquifer. This layer digitized from 1:24000 quad maps into the County's GDMS GIS. It was modified in June 1994 by Spokane County WQMP-GIS and again in March 1995 based on data from additional aquifer studies conducted by CH2Mhill. The Idaho portion of the Aquifer data came from Idaho Panhandle Public Health GIS in March 1993. The Aquifer boundary was redrawn based on new data from a coordinated ground and surface water monitoring program conducted in 2004-2005. The study reassessed the hydrogeology and water budget of the Spokane Valley-Rathdrum Prairie Aquifer (Aquifer). Data was originally digitized at a 1:24000 scale.

Aeromagnetic data were collected along flight lines by instruments in an aircraft that recorded magnetic-field values and locations. In the earlier days of surveying, the only way to represent this data was to generate an analog map with contour lines. This dataset is a representation of the digitized contour lines either by following the lines or by choosing the intersection of the contour and flight-line to create a value of the magnetic field. The values presented are latitude, longitude, and map magnetic-field values.
