The collection consists of (a) approximately 50 field notebooks from geologic mapping, including field maps showing outcrop locations corresponding to the field notes and in some cases draft copies of quadrangle geologic maps, (b) approximately 20 notebooks and associated sample location maps from the Chesapeake Bay Earth Science Study (CBESS), and (c) 1 notebook from the Hart-Miller Island Monitoring Study. Some notes are in pencil and may be difficult to read.
Beach profiles collected periodically, primarily along the Atlantic coast of Maryland, but also along Chesapeake Bay & tributary shorelines. This collection has not been fully inventoried or catalogued.
Collection consists of paper and electronic files of data from individual wells and springs that have been tested for water quality as part of an ongoing statewide assessment of ground-water quality. Data from the collection is documented in publications and annual administrative reports. Results of groundwater samples collected by the Maryland Geological Survey that were analyzed by the USGS National Water Quality lab have been entered into the USGS National Water Information System (NWIS). Some laboratory results of groundwater sample analyses from state or private labs exist only in paper and spreadsheet format at the Maryland Geological Survey and have not been fully inventoried or catalogeed.
Collection of Data from Aquifer Tests and Other Hydraulic Tests of Subsurface Material from Maryland
The collection consists of Excel files describing each aquifer (pump) test, containing raw data, plots, and calculations of hydraulic properties (currently Coastal Plain only) and a list of references associated with the collection. Approximately 262 well locations currently have digital aquifer test data; approximately 345 well locations have hydraulic properties described in a published report. This collection will continue to expand as data from additional wells is acquired. The long-term goal is to incorporate pump test data from non-Coastal Plain provinces/Piedmont of Maryland as well.
This collection includes paper originals and photocopies of reports beginning in 1936, and PDF scans of these reports, up to 1995. In more recent years, this information is available from the Wisconsin DNR via a computer database. Materials are arranged by county and PLSS locations. There are 326,385 well construction reports in this collection.
The Montana Bureau of Mines and Geology (MBMG) Mining Property File collection was amassed over the years through private and industry donations of engineering and geologic reports, pictures, correspondence, news clippings, and production information. The collection presently contains over 4,400 property-specific files (records). The physical files are organized first by Montana county and then by mine or project name. Files may contain information related to a particular mining claim, a collection of claims, or a mining exploration project. Metadata describing each record includes property name, location (county, historical mining district, township, range and section), georeferences (latitude and longitude), and...
Collection includes scanned geological maps managed by the Geological Survey of Alabama. This collection has not yet been inventoried and cataloged. Please contact the Geological Survey of Alabama to inquire about this collection.
Collection of paper reports comprised mainly of IGS publications. A complete list of scanned publications can be found: https://www.iihr.uiowa.edu/igs/publications/search.
There are over 1,000 individual logs from over 450 different holes across the state. Holes include municipal wells, monitoring wells as well as deep and shallow drill holes. Logs collected may include: gamma, caliper, single point resistivity, self potential, normal resistivity, fluid temperature, fluid conductivity, flow meter - heat pulse, flow meter- spinner, optical borehole imager, and acoustic borehole imager. Locations of boreholes and PDF images and LAS files for more than 700 Geophysical Logs can be viewed at https://data.wgnhs.wisc.edu/data-pres-2018/ . New logs are added to this online map as they are added to the WGNHS sample tracking system, Geobase.

American Metal Climax, Inc. (AMAX) added coal production to its diverse mining, metals, and energy concerns on November 1,1969 through a mutually approved merger with Ayrshire Collieries Corporation of Indiana. Ayrshire boasted a long and productive lineage, originating with the first mines established by Scottish immigrant, David Ingle, in the early 1850s near Evansville, Indiana. The Ayrshire name persisted through subsequent purchases of mine shafts by Electric Shovel Coal Corporation in 1927 and a merger with the Patoka Coal Company in 1939, but was rebranded as AMAX Coal Company on January 1, 1972. It became America's third-largest coal producer by 1975. Drilling records in this collection relate to the company's...
