Jack,
I can make out only the north end of this feature, and then
only when the seeing settles. It seems to terminate at a
small crater. This is with my 120mm at 227x.

Running north from the crater Birt and parallel with Rupes Recta the
Straight Wall, is a cleft called Rima Birt that is supposed to be
visible in larger telescopes according to Rukl's. I can see it with the
Club 6", barely with 90x and definitely at 250x. Very very fine. The
cleft and the wall both end simultaneously at their north ends. John
Holmquist knew how to grind a mirror.
