Korolev X is a well-worn, 26 km diameter crater on the lunar farside. Sometime after its formation a nearby impact dug a fresh 13 km diameter crater, breaching Korolev X’s northern wall and sending a tongue of debris tumbling onto its flat floor. Cascading down this debris is a 13 by 5 km sheet of dark and smooth impact melt, still showing the shrinkage cracks that formed as it cooled. The melt didn’t advance as a single flood, but rather on many glacier-like fronts, each several hundred meters across (B). As the melt spread onto Korolev X’s floor overlapping fronts wrapped around high points leaving kipuka-like islands of older more heavily-cratered terrain (C). Location: Latitude 0.56, Longitude -159.44
