In this VIS image, taken by the NASA - Mars Odyssey Orbiter on November, 21st, 2013, and during its 53.285th orbit around the Red Planet, we can take a look at a small portion of the Escarpment that encircles the huge Shield-Volcano known as Olympus Mons. This picture, in particular, shows us a portion of the Escarpment that is located on the South/Eastern Flank of the Volcano.

Just out of curiosity, you may want to notice two small "Pyramidal-like" rocky reliefs which are found towards the North/Eastern portion of the frame itself. The physical configuration of this (however unusually-looking) kind of Surface Features - in a way, not too uncommon on Mars - could be related (due) to the joint action of Major (---> Dominant and powerful) Winds which, by blowing on the original Feature for eons - and, from time to time, also from different directions - shaped the original unearthed Rocky Blocks in what could look like a couple of Twin-Pyramids, both with an almost perfect triangular base.

What else to say about them? That they are just true unbelievable Wonders of the Nature, in our opinion, as IPF...

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 17895) 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.
