View of the northern part of the Deuteronilus Mensae region
Individual mesas up to 30 kilometres across rise as ‘outliers’ from the plain in the transition zone from the Martian highlands further south (left) to the northern lowlands (right). Deuteronilus Mensae is a very typical region for this ‘dichotomy boundary’ on Mars. The 2000-metre-tall mountains show that the Mars highlands previously extended further north but were largely flattened by erosive processes. Glacial ice and flowing water carried highland debris northwards into the lowlands. Traces of the glaciations can be seen particularly well between the mesas, in the form of various linear structures.
