At the Edge of an Ejecta Blanket

At the Edge of an Ejecta Blanket
A CaSSIS image shows that this ejecta blanket has incredible color diversity. The objective of this suggestion is to acquire additional coverage with HiRISE and to learn more about the diverse composition here.   
Scour Pits Southwest of Olympus Mons

Scour Pits Southwest of Olympus Mons
Scour pits are poorly understood erosional features. Generally, scour pits are found in and around the enigmatic Medusae Fossae Formation (MFF). High resolution images of the scour pits located in Olympus Mons can help us answer questions about the formation and extent of the MFF by comparing what this area has in common with the MFF to allow scour pits to form.   
Channels in Southern Mid Latitudes

Channels in Southern Mid Latitudes
The objective of this observation is to examine a group of channels. Some are very small and one is much larger. The small channels connect to the larger ones. It may be that a wide valley was created, partially filled with sediment and then later the sediment was eroded by the channels we now see. Pictures like this may help us understand the fluvial history of this place.  
A Small Channel South of Mangala Valles

A Small Channel South of Mangala Valles
This small channel extends south of Mangala Valles for a few hundred miles where in places, it is buried by crater ejecta or lava. The question is, is it fluvial or magmatic? Another question is, if fluvial, could water have flowed from a paleolake further south here? Context Camera images show two distinct terraces where different levels of water or lava flowed through the channel.  
A Landslide Deposit in West Candor Chasma

A Landslide Deposit in West Candor Chasma
This observation is located between previous coverage to the immediate east, north, and northwest. This is a critical area to address a question: is the landslide deposit superimposed by younger light-toned layered rock, or is the light-toned material part of the original landslide deposit (or even a later landslide deposit on top of it)? This also relates to the questions about the timing of light-toned “interior layered materials” deposition versus the opening of the chasm.
