Grenze zwischen Kasei Valles (oberer Bereich) und Lunae Planum Plateau (unterer Bereich) (Foto: 2009-06-10)

A high-resolution view from the Mars Express orbiter of the boundary between the large outflow canyon system Kasei Valles (upper area) and the Lunae Planum plateau (lower left). Kasei Valles runs northward from near Valles Marineris and feeds into the the northern lowlands/ocean basin. North is to the right in the image. The jumbled terrain was scoured by gigantic water flows in the past, which also eroded the upper wall of the 22-mile diameter crater at the right of the image.
