The Wyoming State Geological Survey (WSGS) publishes geologic maps used in mineral exploration, energy resource development, mitigating geologic hazards, and understanding of local geology. The WSGS distributes these maps on its website as Portable Document Files (PDF), Georeferenced Tagged Image File Format Files (GeoTIFF), Keyhole Markup Language Files (KML), Geographic Information System (GIS) shapefiles, and as printed paper copies.
Annual reports to the Idaho governor on mining extraction and exploration efforts in Idaho, 1899-1974. Generated by the now-defunct Idaho State Inspector of Mines. These out-of-print publications may be difficult to acquire, and contained richer information concerning locations and nature of mineral deposit discoveries and extraction activity than the derived U.S. Bureau of Mines or U.S. Geological Survey annual reports Many reports are indicative of the cultural and political environment at the time they were published, and reflect the impact of historical events on industry such as wars and legislation. These publications are valuable to a wide range of researchers including geologists, historians, educators,...

Collection of seismic film canister records from the USGS Hawaiian Volcano Observatory. Seismic monitoring in Hawaii began in 1912 and has evolved considerably since then. The Hawaiian Volcano Observatory now has a seismic network that extends across the entire Island of Hawai'i. Over the years, the monitoring, analytical, and interpretive capabilities of the network has increased. These seismic film canister records were produced by the Hawaiian Volcano Observatory as part of the seismic monitoring network in 1968–1997. They are contained in wooden creates. Crates are stored on a total of 17 pallets, with each pallet containing ~30 crates. Film-reading equipment is also included in the collection.
The Arizona Geological Survey (AZGS) is committed to making its geologic products freely available online to a variety of consumers of geologic information and data. To this end, AZGS proposed two projects under the 2021-2022 National Geological and Geophysical Data Preservation Program (NGGDPP) to increase the availability of its data. First, AZGS converted 32 of its older geologic maps that existed only as PDF scans into modern digital geodatabases. Each of these preserved maps was then archived and re-published at the National Digital Catalog, University of Arizona Campus Repository, Arizona Geological Survey Repository, and National Geologic Map Database. Second, AZGS participated in the annual Earth MRI workshop,...

A joint project between Nevada Bureau of Mines and Geology and New Mexico Bureau of Geology and Mineral Resources this Journal was published between 1971 and 1996. Its purpose was to provide geochronological datasets focused on the western United States and the world. Latitude and Longitude data is regional since many articles had multiple states or counties.
During the period 1991 to 1997, NCGS staff Geologists John G. Nickerson and Norman K. Gay (Kenny.Gay@ncdenr.gov) mapped the Coastal Plain portion of the Raleigh 100K sheet. For the subsurface analysis associated with this mapping, 392 boreholes were drilled in an area that included the following quadrangles: Angier, Bailey, Clayton, Edmondson, Flowers, Fuquay Varina, Garner, Knightdale, Kenly East, Kenly West, Lucama, Lake Wheeler, Middlesex, Powhatan, Stancils Chapel, Selma, Spring Hope, and Zebulon. Many of the boreholes were drilled by Patterson Exploration Services, Inc., of Sanford, NC. Total footage drilled was 10,089 ft using a variety of drilling methods (e.g. split-spoon sampling, machine and hand augering);...
The North Carolina Geological Survey’s Coastal Plain Office and Core Repository (CPO) serves as the permanent archive for geologic and geophysical data from the NC Low-Level Radioactive Waste Project. Currently, the collection for the potentially suitable Wake/Chatham site includes 18,184.6 ft of core collected from 159 boreholes with a maximum penetration depth of 560 ft. Borehole records for these drill sites exist as paper data in flat files at the CPO. Photographs of the core are available as prints. Additional information on the geology or geophysics of the site remain in unsorted archives stored in ~300 boxes. Electronic archives were not provided when the project was abandoned in 1995. Additional information...
