Pangboche crater (10. 4 km in diameter) lies close to the summit of Olympus Mons volcano, Mars, at an elevation of ~ 20. 9 km above the datum. These increasingly high resolution views show the crater just south of the caldera of the volcano (top left), an oblique view of the entire crater (top right), the terraces on the inner western wall (middle right) and the sequence of uplifted lava fl ows in the wall (bottom). Mouginis‐Mark discusses on pages 51–62 how the geomorphology of the crater may have been influenced by the lack of volatiles in the target and the thin atmosphere at this elevation at the time of formation, and contrasts Pangboche crater with more typical fresh craters found at lower elevations.
