In this VIS image, taken by the NASA - Mars Odyssey Orbiter on February, 15th, 2014, and during its 54.009th orbit around the Red Planet, we can see a large and very dark Windstreak (as you know, one of the most common Aeolian - such as Wind-caused/related - Features found on Mars) that is visible near an ancient and highly eroded Impact Crater with Pedestal, located on the Tharsis' Volcanic Lava Flows, to the East of the gigantic Shield-Volcano known as Olympus Mons. The direction of this (however, unusually-looking) Windstreak tells us that the Dominant Winds in the Region blow from the South/East to the North/West.

This image (which is a crop taken from an Original Mars Odyssey Orbiter b/w and Map-Projected frame published on the NASA - Planetary Photojournal with the ID n. PIA 18195) has been additionally processed, magnified to aid the visibility of the details, contrast enhanced, Gamma corrected and then colorized in Absolute Natural Colors (such as the colors that a human eye would actually perceive if someone were onboard the NASA - Mars Odyssey Orbiter and then looked down, towards the Surface of Mars), by using an original technique created - and, in time, dramatically improved - by the Lunar Explorer Italia Team.
