In George's photo, the location of Dorsa Argand is very near the upper margin of the frame, immediately northeast of the pronounced peaks of Montes Harbinger and east-southeast of the bowl shaped crater Angstrom.- DannyCaes Aug 17, 2011

There's some sort of "upside-down" rille, or very thin ridge, at Dorsa Argand: http://bit.ly/2zmQH6G
Is it a "lunar vein"? A tunnel? Or just a very thin ridge?
