Wolf Creek impact crater

Wolf Creek impact crater

. This relatively well-preserved crater near Wolf Creek, Australia, is partly buried under windblown sand. Iron meteorites have been found in the vicinity, as well as some impact glass. The rim diameter of this crater is 850 meters and the impact that created it occurred about 300 thousand years ago. (Courtesy of Virgil L. Sharpton and the Lunar and Planetary Institute.)
