Although considerably wider and longer than the largest of the depressions described in  Figure 224, this one otherwise closely resembles them. It probably formed in the same way; that is, by collapse into a fissurelike cavity caused by the withdrawal of mare basalt. Closer viewing (and greater enlargement of the original frame) clearly reveals signs of mass wasting. Note the incipient slump fractures along the right rim and large fragments along the right wall and in the bottom of the depression.   -G.W.C.
