A lobate scarp (the visible part of a deep fault that distorts the surface) in the mare basalts of Aitken Crater on the moon's far side. The crater is of great interest to scientists. The smooth mare basalts that flooded the floor of Aitken Crater are relatively few in number on the lunar far side. Mare basalts often have wrinkle ridges and lobate scarps, tectonic landforms that express contraction of the volcanic flows. Future missions to Aitken Crater will explore this formation in search of clues to how this and other lobate scarps form. Image width is 4.5 km, NAC frame M103374879RE.
