o Sinuous Ridge Cutting Across Geologic Units of the Medusae Fossae Formation

At this location is an exceptionally long sinuous ridge, possibly an inverted fluvial feature.

This colorful scene is situated in the Noctis Labyrinthus, perched high on the Tharsis rise in the upper reaches of the Valles Marineris canyon system.
