About this image

The steep canyon walls and ridge forming layers of Valles Marineris are on display in this THEMIS picture. Landslides and gullies observed throughout the image are evidence of the continued erosion of the martian surface. Upon close examination of the canyon floor, small ripples that are likely migrating sand dunes are seen on the surface. Some slopes also display an interesting raked-like appearance that may be due to a combination of aeolian and gully forming processes. Subtle layering is seen at the top of the canyon walls.
