This elongated depression is about 78 km in length, opens from just under 10 km wide at one end to 25 km wide at the other, and reaches a depth of 2 km. It is located at about 21°S / 55°E, just south of the large Huygens crater. The High Resolution Stereo Camera (HRSC) on ESA’s Mars Express took this image. It was obtained during orbit 8433 on 4 August 2010 and has a resolution of about 15 m per pixel. The image was derived from the HRSC nadir channel, which provides the highest detail of all the channels.
