R1: Fra Mauro is almost flooded and has eroded crater walls; some areas of the wall are non-existent. Only the rim in the NE seems to remain; Bonpland and Parry have impacted the southern walls. Crater floor appears rough. Apollo 14 landing site just north of the crater appears to be a higher elevation.
R2:  Parry appears to have a few breaks in its rim that do not appear to be very high. Bonpland is more like a ghost crater, perhaps filled with lava or covered with ejecta blanket. 

 

C1:  Rimae Parry has more than one section:
   * Section 1 crosses the SE rim of Parry in a NE direction before crossing the east rim and continuing a short distance into the Mare.
   * Section 2 extends from the crater Tolansky across the west side of Parry and into the Fra Mauro crater.
   * Section 3 crosses the north rim of Bonpland and into Fra Mauro.
C2:  Dorsum Guettard begins at the southwest rim of Bonpland and ends somewhere around Crater D. It does have a slight curve to it.
