Intersection between Hyblaeus and Elysium Chasmata (EDM n.2 - Saturated Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga - Lunexit Team)

One fresh-appearing streak divides around a slight ridge in this extra-detail mgnf n. 2 (about 1 Km across). Other smaller, fainter, possibly older streaks have formed on either side of this ridge, producing a herringbone-like pattern.
A number of explanations have been suggested for these streaks, including the idea that they are formed by dry avalanches of dust.
