In this (relatively) recent VIS image, taken by the NASA - Mars Odyssey Orbiter on January, 23rd, 2014, and during its 53.722nd orbit around the Red Planet, we can see a few of the most common Martian Aeolian Features, such as the so-called "Windstreaks", whose orientation (here, they are extending from East to West, in the Lee of a few Impact Craters with pronounced - meaning: elevated/high - Rims) tells us the direction of the Dominant Wind/s blowing in and all over the Region.

These specific Windstreaks are found on the Volcanic Plains (and Lava Flows) which are located between the large Martian Volcano known as Alba Mons and the Region of Acheron Fossae.

This image (which is an Original Mars Odyssey Orbiter b/w and Map-Projected frame published on the NASA - Planetary Photojournal with the ID n. PIA 18125) 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.
