The area imaged on 4 January 2013, during orbit 11467, lies just south of the Coprates Catena region of Vallis Marineris, in Thaumasia. The smaller rectangle shows the region covered in this ESA Mars Express High-Resolution Stereo Camera image release highlighting two 50 km-wide craters. The northernmost is called Arima, while the southernmost remains unnamed. NASA MGS MOLA Science Team
