    Wrinkle Ridges Reveal Recent Activity
    After the mare basins were flooded with basalt lava, they contracted. As they contracted, the basalt broke and folded, forming wrinkle ridges. Scientists believe that the fields of boulders on the ridge slopes, possibly shaken loose by moonquakes, could be related to recent shrinking of the Moon. The Moon, it seems, is not "dead" but still geologically active.
