o Basin in the West Candor Chasma Layered Deposits

Wind is a powerful, erosive force, transporting fine-grain sediments that can shape topography and expose darker material underneath the surface.

o Oxbows and Cutoffs in Idaeus Fossae

As rivers age they can meander and occasionally these meanders get so pronounced that the river cuts off these curving loops at their narrow end leaving them as isolated as oxbow lakes.

o Breaching a Crater Rim in Tartarus Montes

In this observation, we can see a small notch in a crater rim with a well-formed channel, where lava flowed. Did the crater fill to the level of the lava outside?

o Migrating and Static Sand Ripples on Mars

Having operated at Mars for more than seven years, MRO and the HiRISE camera continue to make new discoveries. One of these is that many sand dunes and ripples are moving, some at rates of several meters per year.
