  "description": "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.\n[1] Roddy, D.J.
