HiPOD: 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.
