Digital map of major bedrock lithologic units for the Pacific Northwest: a contribution to the Interior Columbia Basin Ecosystem Management Project

This report is one in a series of digital maps, data files, and reports generated by the US Geological Survey to provide geologic process and mineral resource information for the Interior Columbia Basin Ecosystem Management Project (ICBEMP), a US Forst Se

Digital representation of the Idaho state geologic map: a contribution to the Interior Columbia Basin Ecosystem Management Project

This report provides digital representation of the Idaho state geologic map (Bond and Wood, 1978). This report is one in a series of digital maps, data files, and reports generated by the US Geological Survey to provide geologic process and mineral resou

Digital geologic map of Spokane County and vicinity, Washington and Idaho

The geology of Spokane County and vicinity, Washington and Idaho was compiled from Carrara and others (1995), Joseph (1990), Kiver and others (1979), Miller (written communication, 1995), and Waggoner (1990a, b) for input into an Arc/Info geographic infor

Digital geologic map of the Spokane 1:100,000 quadrangle, Washington and Idaho: a digital database for the 1990 N.L. Joseph map

Geologic data from the geologic map of the Spokane 1:100,000-scale quadrangle compiled by Joseph (1990) were entered into a geographic information system (GIS) as part of a larger effort to create regional digital geology for the Pacific Northwest. The m

Digital representation of the Montana state geologic map in ARC/INFO export format.

This report describes the contents of a digital dataset which consists of four ARC/INFO Export format files. The dataset includes a digital representation of the Montana state geologic map.

Digital geologic map of the Coeur d'Alene district, Idaho and Montana

Geologic data from a generalized geologic map of the Coeur d'Alene mining district by Gott and Cathrall (1980) was entered into a geographic information system (GIS) as part of a larger effort to create a regional digital geology for the Pacific Northwest

Digital maps of compositionally classified lithologies derived from 1:500,000-scale geologic maps for the Pacific Northwest: a contribution to the Interior Columbia Basin Ecosystem Management Project

This report describes the contents of a digital data set (approximately 269 MB) which consists of Arc/Info Export format files and associated macro programs. This report is one in a series of digital maps, data files, and reports generated by the US Geol

Digital maps of low- to moderate-temperature geothermal springs and wells in the Pacific Northwest: a contribution to the Interior Columbia Basin Ecosystem Management Project

This report is one in a series of digital maps, data files, and reports generated by the US Geological Survey (USGS) to provide geologic information for the Interior Columbia Basin Ecosystem Management Project (ICBEMP), a US Forest Service and Bureau of L

Digital representation of the Washington state geologic map: a contribution to the Interior Columbia Basin Ecosystem Management Project

This report describes the digital representation of the Washington state geologic map (Hunting and others, 1961). This report contains an explanation of why the data were prepared, a desctiption of the digital data, and information on obtaining the digit

Mineral Resource Assessment of the Payette National Forest, West-Central Idaho

Most information was obtained from MRDS (U. S. Geological Survey Mineral Resource Data System). The data was put into GSMODS (a USGS designed database). The data was modified by field examination by the authors. An arc output was generated from GSMODS and

Digital geologic map of the Rosalia 1:100,000 quadrangle, Washington and Idaho: a digital database for the 1990 S.Z. Waggoner map

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 di
