Caption:
This Mars Global Surveyor (MGS) Orbiter Camera (MOC) image shows an inverted channel running down, through a valley in the Memnonia Sulci region of Mars. The original channel is gone, as are the rocks through which it cut. The channel floor and/or the material that filled the channel was more resistant to erosion, and thus left standing high as a ridge. Inverted channels and valleys are common on Mars. Many old valley networks have been filled, buried, and in some cases, exhumed and inverted, all across the planet.
