The 7.5-minute Lake Owen quadrangle is located in southeastern Wyoming approximately 25 miles (40 kilometers) southwest of Laramie in the west-central interior of southern Albany County, and covers most of the southern extent of Sheep Mountain, the southeastern extent of Centennial Valley, and a portion of the eastern Medicine Bow Mountains. This relational geodatabase, with georeferenced data layers digitized at the publication scale of 1:24,000, organizes and describes the geologic and structural data covering the quadrangle's approximately 35,954 acres and enables the data for use in spatial analyses and computer cartography. The data types presented in this release include geospatial features (points, lines, and polygons) with matching attribute tables, nonspatial descriptive and reference tables, and ancillary resource files for correct symbolization, in formats that conform to the Geologic Map Schema (GeMS) developed and released by the U.S. Geological Survey's National Cooperative Geologic Mapping Program (USGS NCGMP, 2020). When reconstructed from the geodatabase's vector layers and tabular data that has been symbolized according to specifications encoded in the accompanying style file, and using the supplied Federal Geographic Data Committee (FGDC) GeoAge font for labeling formations and GeoSym fonts for structural line decorations and orientation measurement symbols, this data release presents the Geologic Map as shown on the published GQ-1304 map sheet. These GIS data augment but do not supersede the information presented on GQ-1304.

B10, 74 p., https://doi.org//10.3133/tm11B10. The purpose of this data release is to provide Geologic Map Schema (GeMS)-compliant data for the geologic map of the Lake Owen quadrangle, Albany County, Wyoming. Development 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. These data can be accessed from the National Geologic Map Database (NGMDB) distributed archive of standardized geoscience information for the nation. LakeOwen_GQ1304.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 (LakeOwen_GQ1304.gdb) contains the following elements: --GeologicMap: feature dataset (subdirectory) containing the following feature classes (GIS layers): ----CartographicLines: line layer representing cartographic constructs that have no real-world physical existence, such as cross section lines. ----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. ----GenericPoints: point layer representing the location of mine shafts and prospect pits. ----GeologicLines: line layer representing the locations of dikes, fold axes, and other linear features. ----MapUnitPolys: polygon layer representing the distribution of geologic map units. ----OrientationPoints: point layer representing structure measurements, such as bedding attitudes, foliation attitudes, and small folds. --DataSources: table that lists sources and (or) references used to derive spatial features (points, lines, 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. --Glossary: table that defines and lists sources of terms used in the database. --MiscellaneousMapInformation: table that captures various information directly from the original published map plate. --RepurposedSymbols: table that lists standard FGDC geologic map symbols that have been repurposed for use in this publication.

Lakewood CO 80225 US 303-236-1921 303-236-3200 jhorton@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 National Geologic Map Database (NGMDB). Microsoft Windows 10 Enterprise, Version 1909 (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 extracted and digitized directly 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. Polygon, line, and point features were digitized from the GQ-1304 map and quality assured for completeness. Textual information from the original printed map 'Description of Map Units' section was transcribed into the DescriptionOfMapUnits table. Other textual information on the GQ-1304 map such as Economic Geology, References, and collar data, were transcribed into the MiscellaneousMapInformation table. Horizontal accuracy of point, line, and polygon features is dependent on the accuracy of the 1:24,000 scale source map. Map publication techniques employed in 1976 may have used early computing technologies, resulting 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. Vertical accuracy testing does not apply to this dataset. Robert S. Houston Clarence J.
