The USGS Shoemaker collection is composed of impact crater rocks from Meteor Crater (AZ), Flynn Creek Crater (TN), Sierra Madera Crater (TX), Steinheim Crater (Germany), and several craters in Australia. Of special interest to planetary science are nine bags of fallback ejecta from the Meteor Crater interior. Also in the collection are igneous, sedimentary, and metamorphic rocks from South Africa, Australia, the San Francisco Volcanic Field, the Colorado Plateau, and many other locations throughout the U.S. The USGS Shoemaker Collection is an essential part of the legacy of Dr. Eugene Shoemaker, whose pioneering work in the 1960’s established the new field of astrogeology, including shock metamorphism studies, impact crater modeling, [...]
