Located to the east of Beagle Rupes and Sveinsdóttir crater, a modest-sized impact basin on Mercury now bears the name of Izquierdo. It was named in July 2009 in honor of the 20th-century Mexican painter María Izquierdo. As seen in this NAC image, the floor of Izquierdo is smooth, the result of having been partially filled with volcanic lava. Circular outlines of the rims of “ghost craters” – smaller, older craters that have been largely buried by the lavas that infilled the basin – are visible in a few places on Izquierdo’s floor. The remnants of a buried inner ring are also barely discernable in spots, reminiscent of the image of Munkácsy released last week. There have been more recent impacts into the floor of Izquierdo, resulting in some small, sharply defined crater.
