Alluvial fans are always interesting, because they often show us material that was more resistant to surrounding material and literally stand up in our images. Aside from the beauty of the image, the science goal was pretty clear: to compare the surface textures of this eastern part of an alluvial fan complex with that of an earlier observation we took in 2007.
“Alluvial” refers to materials that are left by the water of rivers or floods, and alluvial fans on Mars can often indicate a watery past.
