Terra Cimmeria highlands
October 9, 2009
This image shows the cratered highlands of Terra Cimmeria. The image contains several long troughs of Sirenum Fossae running primarily from left to right. These features are parallel to semi-parallel paired fractures called graben. In places the graben postdate crater formation. This is best seen where graben cut across the ejecta blanket of the large crater near the right center of the image.
