Description
Clark is a relatively worn-looking crater. Most of its rim has in the past been impacted by numerous small craters particularly in its north-eastern sector, with a very prominant one, approximatley 5 km across, in the south. The western sector of the rim hasn't escaped degradation events either, as massive slumping of material in the region has occurred, which covers approximatley a third of the floor of Clark there. A series of hills and terraces has been produced as a result, but these look worn and smooth; possibly because of further slumping -- an indication as to its makeup -- or, perhaps, due to related impact events occurring around the same time that the crater formed. The floor of Clark is flat and shows a history of numerous, small impact craters that occurred, possibly, around the same time -- they look aged and worn in appearance. One obvious, bright-looking crater just north-west of the central region shows a fresh appearance, however, an additional feature just east of this seems interesting; showing a possible, linear fault running approximately north-southwards for about 20 km -- the downside of which occurred at the western side. - JohnMoore2 JohnMoore2

Additional Information
Nomenclature
- Alvan Clark (March 8, 1804 – August 19, 1887) was an American astronomer and telescope maker. His firm Alvan Clark & Sons ground lenses for refracting telescopes, including the largest in the world at the time: the 18.5-inch at Dearborn Observatory, the 26-inch at the US Naval Observatory, the 30-inch at Pulkovo Observatory, the 36-inch telescope at Lick Observatory (still third-largest) and later the 40-inch at Yerkes Observatory, which remains the largest successful refracting telescope in the world.
- Alvan Graham Clark (July 10, 1832 – June 9, 1897) was an American astronomer and telescope-maker. He was the son of Alvan Clark. In 1862, while testing Northwestern University's Dearborn Telescope in Evanston, Illinois, which was a new 18-inch refracting telescope, he discovered Sirius B, the magnitude 8 companion of Sirius and the first known white dwarf.
- There is also a craterlet called Clark at the Taurus-Littrow Valley (the landing site of Apollo 17). Lewis and Clark (Apollo 17 craters) - "William Clark and Meriwether Lewis began the American exploration of the western territories purchased from France by the young nation. Inspired by Thomas Jefferson, their explorations laid both the psychological groundwork for the future expansion of the United States in the West and the geographical basis for our growth and strength as a free nation."
