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.

L18: Mare Serenitatis. Notice the dark areas around the edges showing differing geological composition
L41: Bessel crater ray. Bessel is the largest crater within Mare Serenitatis. The origin of the ray is unknown.
L71: Sulpicius Gallus. Small crater on SW side of the maria. A large cleft runs from the crater, along the circumference of the maria (NW of crater), part of which is just visible in this image.

L29: Aridaeus Rille (see web cam image) Long linear garben. It is over 300km long and is thought to have been formed when a section of the moon sank between two parallel fault lines.
L50: Cayley Plains (immediately south of L29) This is a smooth plane just like the dark maria except that this plain is light.
L63: Julius Caesar, Boscovich (above L29) Boscovich (left) is one of the darkest spots on the moon. Julius Caesar (right) also contains a dark area towards the north.
 
See webcam image below.

L45: Maurolycus. (see web cam image below) Region of saturation cratering. One of the grandest walled plains on the moon. The height of the west wall is 4500m. The east side may be even higher. The central peak is also very tall.
 
 
 
L29 Rima Ariadaeus
L29 is a long linear garben. It is over 300km long and is thought to have been formed when a section of the moon sank between two parallel fault lines.
L50: Cayley plains. A cayley plain is a smooth area similar to the dark maria except that these plains are light. This type of feature was named after the region in this photo. It is below Rima Ariadaeus, and to the right of  the crater and vertical ridge at the centre of the picture.
L63: Julius Caesar (large crater at the top right becomes darker towards the north (top of the image). Boscovich, the crater to the left, has an even darker floor and is one of the darkest areas on the moon. The crater floor is cracked.
Craters: Julius Caesar (top right, 90km), Agrippa (lower left, 46km) Godin (bottom left, 35km)

Maurolycus & Barocius

L45: Maurolycus. This is a region of saturation cratering. It is also one of the grandest walled planes on the moon. The height of the west wall is 4500m. The east side may even be higher. The central peak is also very tall.
