Saturday Night at the Catena....

 Saturday night, 10-9-2010, I gave a talk at ASEM and showed some of my pictures.  A member asked about the catena in the picture.  I have been checking around since then and this one (or possibly 2) don't seem to be on anyone's list of catena.  Click on the pic to get full resolution.
