A long time ago, this ‘chaotic terrain’, a term used by geologists researching Mars, was formed here after ice thawed under the surface of the highland plateau, flowed away and the resulting cavities collapsed. This is an area about 50 by 40 kilometres, consisting of interconnected depressions, terraced slopes on the sides, and in the far north seemingly ‘chaotic’ hills in a dense arrangement. In its northern part (right, in the image) an unusual landscape is noticeable. Pyrrhae Regio, south-east of Eos Chasma, a side valley of the Valles Marineris, is a typical three-to-four-billion-year-old highland plateau with numerous craters, some of which are already heavily eroded.
