South Mid-latitude Gullies November 19, 2005Posted by jtintle in JPL, Mars, Mars Global Surveyor, NASA, Space Fotos.
|This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows deep gullies cut into the wall of a south mid-latitude crater. Erosion has exposed layers in the upper wall of the crater; it is possible that groundwater seeping through a layer or layers in the wall led to the genesis of the gullies. The banked nature of the gully channels suggests that a liquid was involved.|
