Between 1967 and 1979, USGS scientist Dr. David Roddy conducted a drilling program at Flynn Creek crater. The drilling program produced more than 3.8 km of nearly continuous core from 18 separate drill holes. These samples are now contained in 2,261 standard core storage boxes at the USGS in Flagstaff, Arizona.
