Kasei Vallis

The MGS MOLA instrument context image of Kasei Valles suggests the observed channels may be partly structurally controlled due to their rectilinear pattern. However, the high-resolu- tion THEMIS image shows grooves within the channels that can be interpreted as evidence for fluvial activity. This rela- tionship suggests that the initial channel formation was structurally controlled, and that once formed, the channels provided a conduit for movement of material.
