A first look at the ESP_011341_0980 HiRISE image is memorable, with details so repeated and regular as to motivate me to post a topic about the most unique of Mars landform features.
Will we be defining these as other than terrain, climatic, and geological upon close evaluation?
In this image, these all have core structuring, patterned orderliness, and, the largest have transparent surface shapes which prevent the fans from depositing material in sharply defined areas.
Clearly these structures dominate the scene below the surface as well.
