Mars: 'Shaler' in 'Glenelg' area

The NASA Mars rover Curiosity used its Mast Camera (Mastcam) during the mission’s 120th Martian day, or sol (Dec. 7, 2012), to record this view of a rock outcrop informally named “Shaler.” 

The outcrop’s striking layers, some at angles to each other in a pattern called crossbedding, made it a target of interest for the mission’s science team. The site is near where three types of terrain meet at a place called “Glenelg,” inside Gale Crater.

The area covered by the image spans about 3 feet in the foreground.
