BRIEF DESCRIPTION
54.7_N_177.0_W_
Chappell is an 80 km-wide  crater located on the lunar Far Side in the northern hemisphere just to the north of the crater Debye (Section 88). To the NE are two craters, Tsinger and Tikhov  Chappell is located in a heavily bombarded section of the surface, and much of the outer rim of the crater is overlain by many smaller craters. The northern rim in particular has been almost completely disintegrated, while small craters also overlie the rim to the northwest and southeast. What remains of the rim forms a rounded, somewhat irregular edge to the crater depression. In contrast the interior floor is not notably marked by impacts except for a few tiny craterlets. The interior surface is more level and featureless compared to the rugged terrain that surrounds the crater. Near the midpoint of the floor is a low, rounded central ridge. (Credit: Some of the information used in the section feature descriptions was obtained from wikipedia.org.  Section 80 and this directory was created by Fran Ridge and Ned Haskin of The Lunascan Project).
