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.
