The arcuate ridges shown here are part of the large crater Lambert
R (See
blow-up of Fig. 67) , which is mainly deeply buried and now outlined
by mare ridges and a few isolated remnants of the original rim. This is
one of many examples in which underlying topography is reflected by mare
ridges, thereby suggesting a causal relationship. The ridge segments at
A are probably caused by solidification and sagging of the mare lavas over
the crater rim. Crustal buckling caused by sagging of the lava inside the
crater rim may have formed the inner ridges B and C. The exact origin of
mare ridges is still debatable. -C.A.H.
