Part of the Sirenum Fossae region in the Southern Highlands of Mars. The image shows the region centred at about 28°S, 185°E. It extends about 230 by 127 kilometres and covers 29,450 sq km, roughly the size of Belgium. The image was taken by the DLR-operated High Resolution Stereo Camera (HRSC) on the Mars Express spacecraft during orbit 6547. The image resolution is about 29 metres per pixel and is derived from the HRSC nadir channel, which provides the highest detail of all channels.
