In this VIS image, taken by the NASA - Mars Odyssey Orbiter on August, 30th, 2013, and during its 51.949th orbit around the Red Planet, we can see a small portion of the Martian Region known as Lycus Sulci. On the sides of quite a few of the Hills, Ridges and Canyons that are found all over the Region, there are, as you can see here, Dark Slope Streaks. This specific Features (whose origin is not well known yet) are actually very common in Lycus Sulci (as well as in many other Martian Sites), which is the Complex Ridged Terrain surrounding the Northern and Western Sides of the huge Martian Shield Volcano known as Olympus Mons.

Lycus Sulci is located in the Amazonis Quadrangle of Mars, and it is centered at 24,6° North Latitude and 141,1° West Longitude. Lycus Sulci is approx. 350 Km (such as about 217,3 miles) long and it was so named after a so-called "Classical Albedo Feature".

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 17535) has been additionally processed, magnified, 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.
