The Lunar 100 list contains a selection of the Moon's 100 most interesting regions, craters, basins, mountains, rilles and domes. For more details on the list, see http://the-moon.wikispaces.com/Lunar+100. On this page I have included crops of the image above and described the Lunar 100 objects the crops contain.

L83 Plato. Large dark floored crater at right hand edge of this image.

L19: Alpine Valley. Lunar graben. 80 miles in length

L23: Mons Pico. On the left hand side of the image, below the large crater Plato, is a tall isolated mountain (2500m). In this image it casts a very long shadow. The isolated mountain below it is Pico B. The third isolated mountain Mons Piton is to the S.E of Pico.

L4: Apennines. Imbrium basin rim. This mountain range contains over 3000 peaks and stretches for 400 miles from Mount Hadley to the fine ring plane Erathosthenes on the south.

L27: Archimedes. This is the large crater at the top of the image. It is about 50 miles in diameter. It's ramparts are 1300m tall. The walls are terraced, inside and out.

L24: Rima Hyginus.

L35: Rimae Triesnecker. These faint rills are to the south of L24. Only one of them is faintly visible on this image. From the crater in the middle of L24, go SW past a small crater to a large crater. The rill is just to the right of this crater, and extends to the small crater. It also extends to the south towards a crater in the SSE. Unless you already know what it looks like, you probably will not see it in this image!

L28: Hipparchus is the large crater on the right. It has a peak at the centre and contains a medium sized crater on it's west side.

L47: Alphonsus. On the left is a chain of three craters. From north to south: Ptolemaeus, Alphonsus, Arzachel. There are several ash deposits (dark spots) within Alphonsus (look around the edge). Ejecta from the Imbrium impact basin has cut troughs in the crater wall. The central ridge is probably also due to this ejecta.

L75: Ptolemaeus B. The crater inside Ptolemaeus is Ptolemaeus A. Ptolemaeus B is a saucer like depression to the north of Ptolemaeus A. Not really visible in this image.

L92 Gylden Valley. This valley was created by the Imbrium impact ejecta. To the right of the bright crater above Ptolemaeus.

L15 The straight wall (Rupes Recta). At the bottom of the image. Best example of a lunar fault. It extends for 65 miles in a nearly straight line terminating at the S.E. end in a rather peculiar mountain group. The wall is over 150m tall.

L51 Davy crater chain. Result of comet-fragment impacts. To the left of Ptolemaeus is a small bright crater Davy G. The crater chain extends from here to the west into the irregular shaped crater Davy. Apart from Davy G, the rest of the crater chain is not visible in this image.

L46: Regiomontanus central peak. The irregular shaped crater at the centre of this image contains a mountain that is elongated to the NNW. In this image you can see a black dot at the top of this peak. It is thought that this might be a volcanic peak.
