About this image

This is cropped from an image of the region round Rupes Altai when I had been planning to capture the craters at either end of the ridge but in processing realised I'd captured the small transient feature known as Larrieu's Dam, a straight ridge on the edge of Polybius K which looks like a dam holding back a small lake of the shadow in the crater of Polybius K.
