Mastcam mosaic from the Sol 1686 rover location looking behind the rover (downslope) at the transition point between the Sutton Island and Blunts Point Murray members. Images from Sols 1685-1689 display sedimentary textures of dark-toned manganese-rich sandstones and nearby rocks. Dashed line boxes in the large mosaic are shown as insets along the bottom of figure. Small red outlines show the approximate locations and extent of ChemCam observations. Throughout this transition area, dark-toned sandstones (presumably manganese-rich based on ChemCam observations at three locations) overlie light-toned materials. Insets from left to right: (a) Denning Brook, a manganese-rich fine-grained dark-toned sandstone ChemCam observation; (b) and (c) two light-toned blocks with cross-stratified textures, highlighted with yellow lines, 6 m away from Denning Brook and to the upper left in the large mosaic; (d) dark-toned materials (center of mosaic); and (E1) Newport Ledge, (E2) AEGIS post 1685a, (E3) Sugarloaf Mountain, three thin planar laminated dark-toned sandstones.

Mosaic of the Valles Marineris hemisphere of Mars projected into point perspective, a view similar to that which one would see from a spacecraft. The distance is 1,550 miles (2,500 km) from the surface of the planet. The mosaic is composed of 102 Viking Orbiter images of Mars. The center of the scene shows the entire Valles Marineris canyon system, over 1,240 miles (2,000 km) long and up to 5 miles (8 km) deep, extending form Noctis Labyrinthus, the arcuate system of graben to the west, to the chaotic terrain to the east. Many huge ancient river channels begin from the chaotic terrain from north-central canyons and run north. The three Tharsis volcanoes (dark red spots), each about 15.5 miles (25 km) high, are visible to the west. South of Valles Marineris is very ancient terrain covered by many impact craters.
