The 3002’ length core was extracted from the Redstone Quarry in Conway, NH in 1975 as part of an evaluation of geothermal potential produced by the natural decay of several radioactive minerals present in the Jurassic age Conway Granite pluton. The core extracted from the borehole at the Redstone Quarry is the deepest core drilled in New Hampshire. The Redstone Core project was part of a collaboration between the New Hampshire State Geologist and the U.S. Energy Research and Development Administration. Significant geothermal resources were not found. NHGS estimates that approximately half of the original 3002’ foot core remains in core boxes with sufficient documentation tags to identify the depth intervals each...
The John C. Green Collection (Green collection) contains approximately 365 thin section slides, 17 original field notebooks, published and unpublished maps, over 1000 index cards of petrographical and mineralogical information, as well as georeferenced maps and point data in GIS geodatabase format. The data was collected by Dr. John C. Green between 1956 and 1963 in preparation for his PhD dissertation, The geology of the Errol quadrangle, New Hampshire-Maine (Green, 1960) at Harvard University and the subsequent Geological Society of America Special Paper, Stratigraphy, and structure of the Boundary Mountain anticlinorium in the Errol quadrangle, New Hampshire-Maine (Green, 1964). Of the roughly 365 thin sections,...

This collection includes: Water wells, monitoring wells and geothermal wells. The New Hampshire water well inventory database was initiated in 1984 in conjunction with the passage of state statute RSA 482-B which requires licensing of water well contractors and the submission of well completion reports. These reports provide a record of basic construction details of each well along with general information describing geologic materials and subsurface conditions at the well site. A sustained effort has been made to accurately locate each well on a map and store its location in digital form in a geographic information system (GIS). GPS technology was employed to georeference wells beginning in 1995.
This is a collection of core logs and chemical assays recoverd from the Paddock Lead Mine in Lyman, New Hampshire. The physical bedrock cores are now a part of Bob Whitmore's colllection. These bedrock cores were extracted during the 1970s, to assess the potential souce of precious metals from the Paddock Lead Mine. Although, the original assesments did not support further investigation, more recent chemical assays indicate a greater abundance of precious metals such as silver and copper.
This video collection documents the geology and construction of bedrock wells in the New Hampshire Ground Water Level Monitoring Network. The bedrock wells were created as part of an initiaitve to monitor bedrock ground water levels, in a statewide network, in cooperation with the USGS. Videos were converted from 8 mm cassettes to digitial formats and metadata was created to update the Geological Survey's digital inftrastructure.The hydrologic data within this collection enables drought severity assesment, temporal water level measurments, aquifer response to hydrologic events and general hydrologic trends.
This is a collection of core logs and chemical assays recoverd from the Copperville Mine in Milan, New Hampshire. The physical bedrock cores are now a part of Bob Whitmore's colllection. These bedrock cores were extracted during the 1970s, to assess the potential souce of precious metals from the Coppperville Mine. Although, the original assesments did not support further investigation, more recent chemical assays indicate a greater abundance of precious metals such as silver and copper.

Rock cuttings were collected in 2009. A total of 9 Bedrock monitoring wells were drilled in 5 different formations. Cuttings were collected every 20 feet during drilling. The deepest well was 480 feet. Rotary drilling was the drilling technique used, which produces varying sizes of rock chips. Cuttings were collected and major minerals and the bedrock formations were identified on-site by geologists. Cuttings were bagged, and labeled with all pertinent metadata. A well log was maintained during drilling, and this information may be included in the metadata for the cuttings. Bedrock monitoring well cuttings obtained in 2009

A vast collection of geologic reports (bedrock and surficial) including, but not limited to, bulletins and resource surveys, most with accompanying quadrangle or field maps. Publications date back to the 1950's and include a comprehensive geologic history of the mapping area. A large percentage of these publications are out of print and do not exist in any other form. Some are rare publications, which exist only in the State Geologist's archive. Most of these maps and reports were published by the Department of Resources and Economic Development (DRED) and the New Hampshire State Planning and Development Commission. Geologic information included in these publications has not be reproduced elsewhere, and is only...

This collection is a combination of mostly quad maps (scale 1:62,500), and other miscellaneous maps containing notes and drawings of bedrock delineations. A collection of maps with hand-drawn bedrock geologic data used to create the Bedrock Geologic Map of New Hampshire (Lyons and others, 1997).
This collection contains 15 1:24,000-scale surficial geologic maps throughout NH in Geologic Map Schema (GeMS) format. Specific 7.5-minute quadrangles include Bartlett, Bradford, Center Sandwich, Danbury, Hillsboro Upper Village, Jackson, Jefferson, Lancaster, Melvin Village, Mount Grace, Mount Chocorua, Mount Dartmouth, New London, Royalston, and Squam Mountains. The data preservation work in this project involved converting legacy geologic map schemas to full GeMS compliance. This dataset includes GIS surficial data for each quadrangle in the following formats: Esri geodatabase, shapefile, text, Microsoft Excel, and xml. The deliverables also include a PDF of the geologic map showing surficial geology, description...

The collection of Highway Maps includes 8 NH counties at a scale of 1:31680. Maps have shaded areas denoting specific geology in each county. Highway maps ranging from 1958 to 1963. To our knowledge, this set is complete in its current state. Counties are missing, but there is not a discernible way to retrieve them.
