This is the anaglyph of an image obtained by the High-Resolution Stereo Camera (HRSC) during Mars Express' 411th orbit. The anaglyph works both with red/green and red/blue 3D glasses.

The view shows a strip across the transition region between the extensive land mass Tyrrhena Terra, in the left half of the image, and the large Hellas impact basin. The northern edge of the Hellas basin can be seen running diagonally across the image on the right. North is to the left.

With a diameter of ~2100 km, Hellas is the largest impact crater on Mars. In the Martian southern winter, the basin is often filled with white CO₂ frost, making it stand out even more from the surrounding terrain.

The large area of Tyrrhena Terra is part of the ancient cratered southern highlands on Mars. The terrain is composed of material that is a mixture of ejecta from the Hellas impact, pre-basin remnants, and highland terrain. Subsequent impacts have scarred the area with numerous smaller craters. The region has been weathered further by fluvial and lake deposits, erosion, tectonic movements, volcanic materials and aeolian (wind) processes.

At the lower left border of the image is crater Rungana. This is a small crater with a diameter of ~40 km and a central uplift. It is located at 75.9° E, 26.3° S and is named after a town in New Zealand. Directly south-east of crater Rungana, lies the small crater Jörn with a diameter of ~20.7 km. It is located at 76.3° E, 26.9° S and is named after a town in Sweden.
