In this VIS image, taken by the NASA - Mars Odyssey Orbiter on December, 14th, 2015, and during its 62.101st orbit around the Red Planet, we can see a small portion of the Margin of the Martian Region known as Tempe Terra, near the other large Martian Region known as Chryse Planitia. Several Outflow Channels are visible, as well as Tectonic Features.

The Linear Surface Feature visible below the Major Channel is, most likely, a so-called "Graben", such as an Area of the Surface where two Bounding (and almost parallel) Faults caused the Interior Material to be lower (actually, to fall on itself, or subside) than its surroundings.

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 18259) 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.
