Flynn Creek Crater Drill Core FC67-1

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.

Geologic studies of these drill cores in the 1960’s and 1970’s laid the groundwork for understanding structural deformation during marine target impact crater formation. Recent advances in numerical modeling and analytical techniques for terrestrial impact crater analog studies have provided unprecedented details on the formation of complex impact crater morphology, impact-induced hydrothermal systems, impact melting of sedimentary targets, and mineral shock metamorphism.

Flynn Creek Crater Drill Core FC67-1 contains 39 boxes and reaches a depth of 392 feet (119.5 meters)
