Scans have been grouped and combined into single PDFs that may include maps, letters, news clippings, photographs, and reports. Note that some PDF files are very large. These documents were then related to associated MILO points by DOGAMI personnel. Understand that recreation in or around inactive mine sites is extremely dangerous, and can result in serious injury or death. Stay out and stay alive! County Mine Records is intended for use as reference material for individual MILO points. This data set represents the relationship of documents that have been referenced to specific MILO point(s) in a many to many relationship. 2020 Complete As needed ISO 19115 Topic Category geoscientificinformation Oregon Geospatial Enterprise Office Metadata Keyword Thesaurus stone metallic mineral industrial mineral mineral resource zeolite sand and gravel MILO (Mineral Information Layer for Oregon) Mine Mineral fuel Aggregate Gemstone Borrow Pit Prospect Quarry Gravel Pit Mineral Occurrence Oregon Geospatial Enterprise Office Metadata Keyword Thesaurus North America United States of America Oregon Baker Benton Clackamas Clatsop Columbia Coos Crook Curry Deschutes Douglas Gilliam Grant Harney Hood River Jackson Jefferson Josephine Klamath Lake Lane Lincoln Linn Malheur Marion Morrow Multnomah Polk Sherman Tillamook Umatilla Union Wallowa Wasco Washington Wheeler Yamhill Oregon Geospatial Enterprise Office Metadata Keyword Thesaurus Oregon Geospatial Enterprise Office Metadata Keyword Thesaurus None REPORT DATA: This product is for informational purposes and may not have been prepared for or be suitable for legal, engineering, or surveying purposes.

McClaughry Oregon Department of Geology and Mineral Industries Eastern Oregon Regional Geologist jpeg image (.jpg) The Mineral Information Layer of Oregon Release 3 (MILO Release-3) is a large database developed over several decades by DOGAMIs researchers and reporters. Funding for the compilation of MILO Release-3 during 2018 to 2020 was provided by the U.S. Geological Survey (USGS) National Geological and Geophysical Data Preservation Program (NGGDPP) under assistance award G18AP00102. Unclassified Attribute accuracy is tested by manual comparison of the source and hard copy scans. However some PDFs contain pieces of documentation that are not related to the specific mine listed in the title and other PDFs contain documentation on multiple mines and mine synonyms. Fixing these errors was beyond the scope of this project and no attempt has been made to fix these errors. The detail level (e.g. Title) of the source material and interpretation procedures for capturing that source affect the quality of the data. Not all fields contain applicable attribute and are filled in as unknown. Field checking of the data was not performed. Due to the many to many relationship some CountyMineRecords_IDs may be repeated, and/or some MILO points may be repeated. However no duplicated features exist although individual features may share some of the same attribute(s), but have differences in unique identifiers. Although the data were collected and reported by numerous people, the descriptions provided follow a consistent structure or terminology though the content may vary widely. Not all fields are attributed in the data set. These data are scans of the literature originally found in DOGAMI published and unpublished hardcopy holdings, though some documents may not have been included, the coverage is statewide. The tabular data are presented in the form of rows representing the relationship of the maps, letters, news clippings, photographs, or reports to a specific MILO point. The county mine records are a relationship table and do not have positional accuracy. The county mine records are a relationship table and do not have positional accuracy.

This necessitated a conversion, in which the earlier version of MILO-Release 2 was converted from a ESRIs .shp (shapefile) file format to ESRIs .gdb (file geodatabase) file format by using ESRIs (Version 10.7) Load Data function. DOGAMI updated MILOs file structure to adhere to the Geologic Map Schema (GeMS), designed by the U.S. Geological Survey. The schema can be found here (https://ngmdb.usgs.gov/Info/standards/GeMS/).
