In this really suggestive VIS image, taken by the NASA - Mars Odyssey Orbiter on September, 25th, 2015, and during its 61.129th orbit around the Red Planet, we can see a small portion of the Northern Margin (---> Edge) of Tanaica Montes (approx. 177 Km - such as 109,917 miles - in diameter).

These Hills are heavily cut by Fractures, which are in alignment with the Regional Trend of Tectonic Faulting that has ben found to the East of the huge Martian Volcano known as Alba Mons. Just out of curiosity, you may want to notice that only a few, small, and extremely old, Unnamed Impact Craters can be seen in the pictured area.

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 20099) has been additionally processed, magnified to aid the visibility of the details, extra-contrast enhanced and sharpened, Gamma corrected and then colorized in Absolute Natural Colors (such as the colors that a normal 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.
