This small Ridge, about 3 feet (such as approx. 0,914 meters) long, appears to resist very well to the Wind Action (Erosion) more than the flatter Rocky Plates that can be seen all around it. Such differences are among the Rock characteristics that the NASA - Mars Exploration Rover (MER) - Mars Laboratory Curiosity is examining at selected targets located at the base of Mount Sharp. The Ridge pictured here, and nicknamed "Pink Cliffs", is within the "Pahrump Hills" Rocky Outcrop forming part of the Basal Layer of the Mountain. This view is a mosaic of exposures acquired by the NASA - Mars Exploration Rover (MER) - Mars Laboratory Curiosity Mast Camera (or "MastCam") shortly before a two-week walkabout up the Outcrop, scouting to select which targets to examine in greater detail during a second pass.

Pink Cliffs is one of the targets chosen for closer inspection. This image combines several frames taken with the MastCam on October, 7, 2014, such as the 771st Martian Day, or Sol of Curiosity's work on Mars.

This picture (which is a crop taken by an Original NASA - Mars Exploration Rover (MER) - Mars Laboratory - "Curiosity" White-Balanced image-mosaic published on the NASA - Planetary Photojournal and identified by the ID n. PIA 18880) has been re-processed, reduced in size to fit the page, Gamma corrected and then re-colorized in Absolute Natural Colors (such as the colors that a normal - meaning "in the average" - human eye would actually perceive if someone were on the Surface of Mars, near the NASA - Mars Exploration Rover (MER) - Mars Laboratory Curiosity, and then looked towards the location nicknamed Pink Cliffs, inside Gale Crater), by using an original technique created - and, in time, dramatically improved - by the Lunar Explorer Italia Team.
