This collection contains unpublished hand drawn geologic maps, field maps, traverse maps, sample location maps, and cross sections of Traveler Mountain and vicinity, central Maine. The maps were created by Douglas W. Rankin between 1955 and 1961 (date is indicated if known) and scanned in 2016. Most maps use a 7.5-minute topographic quadrangle as a base. Some compiled maps of larger areas are a composite of several 7.5-minute quadrangle maps and latitude and longitude values are indicated on the map. Please contact the Eastern Geology and Paleoclimate Science Center for additional information and access to original copies.

This data release includes 40Ar/39Ar data from the U.S. Geological Survey for samples from Old Mine Park Area, Trumbull, Connecticut. Mineral samples were collected by Robert Wintsch and Harold Moritz. Potassium-bearing mineral grains were separated from the bulk sample and analyzed by argon geochronology at the U.S. Geological Survey Bascom ARgon Dating (BARD) Laboratory in Reston, Virginia. The data provide age constraints on units in the relevant geologic mapping area.

This spreadsheet contains the results of open-bore auger samples collected by the U.S. Geological Survey in Maryland and Virginia for the Federal Highways Administration Turner-Fairbanks Highway Research Center. 19 sites were selected in 14 different locations across northern Virginia and southern Maryland by FBGC scientists to drill boreholes for the development of the TFHRC’s In-situ Scour Testing Device (ISTD) and to investigate the sedimentological properties of different layers of the near-surface soil column. Each worksheet in this excel workbook contains the detailed log information for one site, including its name, gps coordinates, surface elevation, borehole depth, information about the drilling rig used...
This raster dataset describes elevation values, in meters (m), in Sleeping Bear Dunes National Lakeshore in 1955. The 1955 DEM was produced from historical aerial imagery acquired on April 1, 1955 at a flying height of 8,500 ft (1:17,000). Structure from motion (SfM) analysis of this imagery produced a 0.88 m DEM, which was edited and resampled to 1 m.

This data release contains three spreadsheets that have aluminum-26 and beryllium-10 concentrations for samples collected in and near Sparta, North Carolina in 2021-2022. These samples were prepared for burial dating by the Reston Cosmogenic Nuclide (RECON) Lab and measured via accelerator mass spectrometry at the Purdue Rare Isotope Measurement (PRIME) Lab. The file “Sparta_SiteLocations_Odom.csv” contains site locations and interpreted ages; measurements of aluminum-26 and beryllium-10 and related data are located in respective .csv files.

ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
