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 craterlets. Plato is the large, dark floored crater just above centre in this image. It is 60miles in diameter and has a very smooth flat floor. It contains some tiny craters that are very difficult to observe. They are not visible in this photo.

L19: Alpine Valley. Lunar graben. 80 miles in length. To the right of Plato.

L23: Mons Pico. In the centre 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.

L5 Copernicus. The large crater to the left of centre in this image. One of the most impressive sights on the moon. 56 miles in diameter. The wall to the west is about 4000m tall. The central mountains consist of five small peaks.

28: 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.

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 upper right 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. Also see Lunar 100 68%

L84 Pitatus. Crater with concentric rills. Not visible in this image.

L6 Tycho. This is the bright crater the top centre of the image. The brightest ray system on the moon originates from this crater. It must therefore be a relatively recent crater (in a lunar time scale!). It is 54 miles in diameter, the central mountain is 1700m tall.

L9 Clavius. This large crater at the bottom centre of this image contains an arc of size sorted craters at the bottom centre of this image. Clavius is 142 miles in diameter.
