This lobate scarp marks the location of a relatively young, low-angle thrust fault. The land west of the fault was forced up and over the eastern side as the lunar crust contracted.

In a May 2019 paper published in Nature Geoscience, Thomas Watters and his coauthors provide evidence that this fault and others like it are still active and producing moonquakes today. Seismometers left on the Moon by Apollo astronauts recorded hundreds of events between 1969 and 1977, including 28 shallow moonquakes. The study narrowed the locations of these quakes and found that many of them occurred near scarps, implying that the forces creating the scarps also caused the quakes, and they continue to shape the lunar surface. The Lee Lincoln scarp was only about 13 kilometers from one of the epicenters identified by the scientists.

The Apollo 17 astronauts drove their lunar rover onto the scarp during their second day on the lunar surface, and this remains the only extraterrestrial scarp visited by humans.", "items": [], "extra_data": {} }, { "id": 323662, "url": "https://svs.gsfc.nasa.gov/4714/#media_group_323662", "widget": "Video player", "title": "", "caption": "", "description": "
