In this (relatively) recent VIS image, taken by the NASA - Mars Odyssey Orbiter on January, 17th, 2014, and during its 53.650th orbit around the Red Planet, we can see (at the bottom of the frame) a number of small Channels dissecting the North/Western Flank of the Martian Volcano known as Hecates Tholus. Hecates Tholus is located in the Martian Region of Elysium Planitia, at about 32,1° North Lat. and 150,2° East Long.; Hecates Tholus has a diameter of approx. 183 Km (such as about 113,64 miles) and it is the Northernmost of the three Major Elysium Volcanoes (being the other two Elysium Mons and Albor Tholus).

Remember that in the Planetary Nomenclature, a "Tholus" is a "Small Dome-shaped Mountain" or a "Hill".

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 18101) 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.
