Attribute tables and geospatial features (lines and polygons) conform to the Geologic Map Schema (USGS NCGMP, 2020) and represent the geologic map as published in USGS Miscellaneous Investigations Series Map I-2267 (Harrison and others, 1992). Minor errors, such as mistakes in line decoration or differences between the digital data and the map image, are corrected in this version. The database represents the geology for the 16,436 square kilometer, geologically complex Kalispell 1 x 2 degrees Quadrangle, at a publication scale of 1:250,000. The map covers primarily Flathead and Lincoln Counties, but also includes minor parts of Glacier, Lake, and Sanders Counties. These GIS data supersede those in the interpretive report (Harrison and others, 2000).

B10, 74 p., https://doi.org/10.3133/tm11B10. The purpose of this data release is to provide a Geologic Map Schema (GeMS)-compliant version for the geologic and structure maps of the Kalispell 1 degree x 2 degrees quadrangle, Montana, and Alberta and British Columbia, that updates the geospatial data published as part of U.S. Geological Survey Miscellaneous Investigations Series Map I-2267 (Harrison and others, 2000). Conversion and publication of modern GIS data for geologic maps is foundational and high priority to the USGS Mineral Resources Program (MRP) to facilitate on-going research and other activities pertaining to critical mineral deposits as well as to other geologic and geophysical mapping efforts, petrologic studies, and mineral resource assessments. The data reside in the National Geologic Map Database (NGMDB) distributed archive of standardized geoscience information for the nation. Kalispell_1x2degrees.gdb is a composite geodataset that conforms to "GeMS (Geologic Map Schema) - A standard format for the digital publication of geologic maps," available at http://ngmdb.usgs.gov/Info/standards/GeMS/. A shapefile version of the dataset is also available. It consists of shapefiles, DBF files, and delimited text files and retains all information in the native geodatabase, but some programming will likely be necessary to assemble these components into usable formats. The Esri file geodatabase (Kalispell_1x2degrees.gdb) contains the following elements: --GeologicMap: feature dataset (subdirectory) containing the following feature classes (GIS layers): ----ContactsAndFaults: line layer representing locations of contacts and faults. ----DataSourcePolys: polygon layer representing the spatial extent of data sources and (or) references used within the map boundary. ----GeologicLines: line layer representing the locations of dikes, fold axes, and other linear features. ----MapUnitPolys: polygon layer representing the distribution of geologic map units. --DataSources: table that lists sources and (or) references used to derive spatial features (lines and polygons) and attribute information. --DescriptionOfMapUnits: table of map unit descriptions derived from the collar of the geologic map or geologic map pamphlet. The hierarchical order of map units is coded in the HierarchyKey field. --GeoMaterialDict: table that defines and lists lithology terms in hierarchical order used in the GeoMaterial field of the DescriptionOfMapUnits table. The standardized vocabulary is available in Appendix 1 of the GeMS documentation, available at https://doi.org/10.3133/tm11B10. --Glossary: table that defines and lists sources of terms used in the database.

Lakewood CO 80225 US 303-236-5600 303-236-3200 klund@usgs.gov Work was accomplished by the U.S. Geological Survey Geology, Geophysics, and Geochemistry Science Center (GGGSC) with support from the Mineral Resources Program (MRP) and the FEDMAP component of the National Cooperative Geologic Mapping Program. Microsoft Windows 10 Enterprise, Version 10 (Build 18363); Esri ArcGIS Pro 3.4.3 Unique values in attribute fields were checked through frequency analyses. The unique values in each attribute field were reviewed and checked for spelling, consistency of terms, accuracy, adherence to established vocabularies, and completeness. Text terms and values entered by USGS authors were reviewed and verified. GIS layer and attribute information were cross walked into the GeMS database structure. Attribute values were modified for consistency with GeMS terminology. Topology tests were conducted on polygon and line feature classes to ensure spatial integrity of the data. The original GIS database (Harrison and others, 2000) was converted from ArcInfo interchange files (E00) to an Esri file geodatabase. Minor errors, such as mistakes in line decoration or differences between the digital data and the map image, are corrected in this version. The data set is considered complete for the information presented and as described in the abstract. Horizontal accuracy of line and polygon features is dependent on the source data. Computing technologies used for original data capture resulted in variable line quality and accuracy. Estimated accuracy of horizontal location, provided on a per-feature basis in the attribute field LocationConfidenceMeters in GeMS, was assigned a value of -9 indicating unknown. Base maps and/or materials used for original data capture (ArcInfo coverages) are no longer available. Registration discrepancies between the printed map and the digital data are not addressed in this version. Vertical accuracy testing does not apply to this dataset. Jack E. Harrison Earle R.

Harrison and others (1992) compiled the geology and published the original geologic paper map at 1:250,000 scale. The geologic map was scanned, digitized, and prepared as ArcInfo coverages by Earth Resources Observation Systems (EROS) Data Center prior to 1994. The data were later converted to topologically correct ArcInfo coverages, attributed, and published by Harrison and others (2000). Harrison and others (1992) 2000 The original data (Harrison and others, 2000) were converted from ArcInfo interchange files (E00) format into feature classes within an Esri file geodatabase. Attributes were standardized to conform to the Geologic Map Schema (GeMS) standard for geologic map publications (USGS NCGMP, 2020). Definitions of these values are derived from the source publication (Harrison and others, 1992), GeMS (USGS NCGMP, 2020), and from the Glossary of Geology (Neuendorf and others, 2011). GeMS geodatabase feature classes and tables were populated with additional information as required. Data layers were re-projected to Albers Equal Area, North American Datum 1983, in units of meters. Base maps and (or) materials used for original data capture are no longer available, therefore a georeferenced version of the original map publication (https://ngmdb.usgs.gov/Prodesc/proddesc_10204.htm) from the National Geologic Map Database was used to compare attribute information and to correct minor discrepancies between the GIS data and the printed map. Minor errors, such as differences in line decoration, line type, or map units were corrected and documented in the Notes attribute field. Registration discrepancies between the printed map and the digital data are not addressed in this version. Map unit colors were matched to the original publication as best possible and are provided as RGB values in the AreaFillRGB field of the DescriptionOfMapUnits table. Map unit colors are also provided in the custom Esri Style file. Geologic map symbolization was also matched to the original publication as best possible using the FGDC Digital Cartographic Standard for Geologic Map Symbolization (FGDC, 2006). These values are provided in the Symbol attribute fields and in the included Esri Style file. Topology tests were conducted on polygon and line feature classes to ensure spatial integrity of the data. The geodatabase was confirmed to be GeMS compliant using validation tools. The 'Index to Sources of Geologic Data' index map shown on the printed map was digitized and included in the DataSourcePolys polygon layer and DataSources table as a courtesy. These are the sources used to produce the original printed geologic map; they are not the sources used to produce the original GIS data (Harrison and others, 2000).

Description [Descr] (DescriptionOfMapUnits, ContactsAndFaults, GeologicLines) Free-format text description of map unit or the Type and certainty of a line feature. Commonly structured according to one or more accepted traditions (for example, lithology, thickness, color, weathering and outcrop characteristics, distinguishing features, genesis, age constraints). USGS NCGMP (2020) Examples of values: "Gravel, sand, silt, and clay in flood plains and low terraces along present drainages" or "fault, normal, concealed" DescriptionOfMapUnits_ID [DMapUns_ID] (DescriptionOfMapUnits) Unique alpha-numeric value assigned to each feature (primary key). USGS NCGMP (2020) Values are unique within this database. Example of values: "DMU01" DescriptionSourceID [DesSrcID] (DescriptionOfMapUnits) Source(s) of map unit description; alpha-numeric value used to link to DataSources table (foreign key). USGS NCGMP (2020) Values are unique within this database. Multiple values concatenated. Examples of values: "DAS02" and "DAS02 | DAS20 | DAS25"; see DataSources_ID attribute information. ExistenceConfidence [ExiConf] (ContactsAndFaults, GeologicLines) Confidence that feature exists. USGS NCGMP (2020) certain Identity of a feature can be determined using relevant observations and scientific judgment; therefore, one can be reasonably confident in the credibility of this interpretation. USGS NCGMP (2020) unspecified Used for the boundary of a map where no confidence is specified. USGS NCGMP (2020) FullName (DescriptionOfMapUnits) Name of map unit including identification of containing higher rank unit(s). USGS NCGMP (2020) Example of values: "Siltite facies of the Bonner Quartzite" GeologicLines_ID [GeoLin_ID] (GeologicLines) Unique alpha-numeric value assigned to each feature (primary key).

Example of values: "GEL001" GeoMaterial [GeoMat] (DescriptionOfMapUnits, GeoMaterialDict) Categorization of map unit based on lithologic and genetic character, term selected from NGMDB standard term list defined in Appendix 1 of GeMS documentation. USGS NCGMP (2020) Example of values: "------Mafic-composition lava flows" or "------Sandstone and mudstone" GeoMaterialConfidence [GeoMatConf] (DescriptionOfMapUnits) Describes appropriateness of GeoMaterial term for describing the map unit. USGS NCGMP (2020) High The term and definition adequately characterize the overall lithologic nature of rocks and sediments in the map unit. Regarding the subjective term "adequately characterize", we refer to context and objectives of this classification as described in the GeMS documentation. USGS NCGMP (2020) Medium The term and definition generally characterize the overall lithology of the map unit, but there are one or more significant minor lithologies that are not adequately described by the selected term.
