It has been known since the 1970s when the Viking orbiters took pictures of Mars that there are large (i.e., several kilometers-thick) mounds of light-toned deposits within the central portion of Valles Marineris.
Exposed Fractured Bedrock in the Central Pit of a Crater
This HiRISE image shows the central pit feature of an approximately 20-kilometer diameter complex crater in located at 304.480 degrees east, -11.860 degrees south, just north of the Valles Marineris.
Hematite-Rich Deposits in Capri Chasma
Capri Chasma is located in the eastern portion of the Valles Marineris canyon system, the largest known canyon system in the Solar System. Deeply incised canyons such as this are excellent targets for studying the Martian crust, as the walls may reveal many distinct types of bedrock.
Plains South of Valles Marineris
This enhanced-color sample reveals the incredible diversity of landforms on some Martian plains that appear bland and uniform at larger scales.
