The right Mast Camera (Mastcam) of NASA’s Curiosity Mars rover provided this view of the lower stratigraphy at “Yellowknife Bay” inside Gale Crater on Mars. The rectangle superimposed on the left image shows the location of the enlarged portion on the right. In the right image, white arrows point to veins (including some under the overhang), and black arrows point to concretions (small spherical concentrations of minerals).
