Iani Chaos is one of many regions east of Valles Marineris characterized by disrupted or chaotic terrain. The morphology of this terrain is dominated by large-scale remnant massifs, which are large relief masses that have been moved and weathered as a block. These are randomly oriented and heavily eroded. To the south (south is to the left) in this image, these mesas, which appear as flat-topped hills, range from less than one kilometre to roughly 8 kilometres wide, with a maximum relative elevation of approximately 1000 metres.

This colour image was captured on 14 October 2004 by the High-Resolution Stereo Camera (HRSC) onboard the ESA spacecraft Mars Express with a ground resolution of approximately 13.0 metres per pixel.

This map shows the location of Iani Chaos, lying at approximately 0.7° South and 340.6° East, just south of Aram Chaos. Scientists believe that Iani Chaos was the source of the fluids thought to have created Ares Vallis, the roughly 1500-kilometre-long valley that extends to the north-west in the direction of Chryse Planitia.

Iani Chaos, 3D anaglyph
Download:
  HI-RES JPEG (Size: 3836 kb)  HI-RES TIFF (Size: 21 055 kb)
This 3D anaglyph is based on data captured by the High-Resolution Stereo Camera (HRSC) onboard the ESA spacecraft Mars Express. Accompanying colour scenes were derived from the three HRSC colour channels and the nadir channel, while this anaglyph image was calculated from the nadir and one stereo channel.
