Fretted Terrain Valleys
Caption:
30 October 2004
This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows shallow tributary valleys in the Ismenius Lacus fretted terrain region of northern Arabia Terra. These valleys exhibit a variety of typical fretted terrain valley wall and floor textures, including a lineated, pitted material somewhat reminiscent of the surface of a brain. Origins for these features are still being debated within the Mars science community; there are no clear analogs to these landforms on Earth. This image is located near 39.9°N, 332.1°W. The picture covers an area about 3 km (1.9 mi) wide. Sunlight illuminates the scene from the lower left.
