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, and was probably caused by the impact of a train of projectiles. Several small channels on the blanket suggest an impact into a volatile-rich surface (box 1). There are three deeper areas within the basin. This could be evidence for several projectiles (box 2). Several landslides that took place after the impact have modified the steep crater rim. The best examples of this are two smaller craters on the rim, which are only partially preserved (box 3). Close to the eastern crater rim, two well-formed and relatively deep craters are almost pristine (box 4). To the north of the box is another crater but this one has been modified by the creation of the ejecta blanket. The data were acquired during orbit 8433 on 4 August 2010 using the High Resolution Stereo Camera on Mars Express.
