BRIEF DESCRIPTION
43.9_S_119.9_E
Ridge Section 148 is entitled Van der Waals, named after a 104 km-wide crater on the lunar Far Side. It is a heavily eroded feature with an irregular outer rim. The edge is lowest along the southern side where it is little more than a circular crest along the ground. It is more developed along the northern side, but the rim is notched and rugged. The satellite crater Van der Waals W is attached to the exterior of the northeast, and Van der Waals H intrudes into the rim along the southeast. The interior floor is relatively even and featureless, with only a few tiny craterlets to mark the surface. Nearby craters of note include Clark to the north, Carver to the east, and Pikel'ner to the southeast. Lebdev, Lamb and Parkhurts are also in the frame but can't be delineated due to the extreme curvature of the lunar limb near Mare Australe. However the cropped-to-fit colored USGS chart does show Lamb, but it appears to be out-of-frame in our section.  It is very difficult to point these out on the images above. The best way to view them is by clicking on the LRO WAC 117 link above. About two crater diameters to the west-southwest is Lebedev, on the bottom left of that chart.

Section 148 and this directory was created by Fran Ridge and Ned Haskin of The Lunascan Project).
