Ridge Meets Butte The curved ridge is darker than surroundings and appears to be an inverted stream channel. At this location, the inverted stream is interrupted or diverted by the presence of a couple of buttes or knobs. The main objective here is to get very high resolution coverage of the inverted stream materials (sedimentary rock?) and to include the buttes and attempt to discern their origins and relations to the old stream channel system.
Hills in Eos Chasma These hills are surrounded by small gullies, where there is likely activity related to recurring slope lineae, perhaps even slumps, which are masses of loosely consolidated material or rock layers that move a short distance down a slope. These features are similar to well-monitored hills in Juventae Chasma. Eos is located in the southern part of the Valles Marineris canyon system.
From Smooth to Collapsed This region marks a transition from the smooth to hummocky surface typical of the Arsia Mons western summit to a collapsed terrain. The formation of the collapsed terrain appears to represent some of the youngest activity on the western flank and understanding the formation of these two units is critical for interpreting the developmental sequence of the shield.
Mounds in Oxia Colles This landform shows distinctive layering in Context Camera images and is similar to other buttes to the far north east which have been observed to have Mawrth-like stratigraphy. Understanding the connection between these landforms is vital to our knowledge of their formation. Highest resolution will allow for viewing of sedimentary structures.
