Tenielle A. Gaither Justin J. Hagerty Haley Demircan 2025 pdfs, jpegs https://doi.org/10.5066/P14NBDFV Flynn Creek crater is a ~3.8 km diameter, >200 m deep, flat-floored impact structure that formed ~360 Ma in what is now north-central Tennessee (36°17’ N, 85°40’ W) [1-4]. Between 1967 and 1979, USGS scientist Dr. David Roddy conducted a drilling program at Flynn Creek crater, an invaluable terrestrial analog that can be applied to the field of planetary impact cratering dynamics [5,6]. The drilling program produced more than 3.8 km of nearly continuous core from 18 separate bore holes [7]. These samples are now contained in 2,621 standard core storage boxes at the USGS in Flagstaff, Arizona and each box has been photographed. [1] Roddy, D.J.

The Flynn Creek Crater Sample Collection has been curated following the evaluation criteria for preservation established by the USGS Geologic Collections Management System (GCMS) and is available for check out to professional scientists. Drilling at Flynn Creek crater was carried out by USGS scientist David Roddy in the 1960s and 1970s with the goal to acquire detailed morphologic, structural, and shock metamorphic data on flat-floored craters with central uplifts [1]. These drill cores are currently stored at the USGS Flagstaff, AZ Science Campus and are available to the science community for research. Each core box has been photographed to increase accessibility and discoverability, 2016 2017 Time range photos were taken.

Flagstaff AZ 86001 N/A agullikson@usgs.gov Drilling and subsequent work supported D. Roddy through the cooperation of NASA under Contract W-13, 130 and the Defense Nuclear Agency, Department of Defense. Curation of the drill cores was supported by NASA through the Planetary Geology and Geophysics program via grant NNH14AY73I, and its continued curation and preservation is funded through an inter-agency agreement between NASA and the U.S. Geological Survey Astrogeology Science Center Microsoft 365, version 18.2301.1131.0.

Each photograph includes the drill hole number, box number (i.e., box 3 out of 24 boxes), the vertical depth range, both in feet and meters, a scale in inches, and a color scale to calibrate color. This data was based on the information written on each core storage box. Data duplication has been checked. This data represents rocks sampled from Flynn Creek crater, and therefore, represents a fixed and unique geographic area. A multi-year drilling program was carried out by USGS David Roddy from 1967 to 1979. Drill holes are labeled as FCYY-# (Flynn Creek, year hole was drilled, and hole number). 1979 Core sample box information was entered into a database, damaged boxes were replaced, and each core box was photographed using a CANON EO6 60D. 2017 Drill core photographs from Flynn Creek Crater in Jackson County, Tennessee.
