This picture (centered at latitude 4 degrees S., longitude 76 degrees W.) shows parts of central Valles Marineris, including Candor Chasm (lower left), Ophir Chasm (lower right), and Hebes Chasm (upper right). Complex layered deposits in the canyons may have been deposited in lakes, and if so, are of great interest for future searches for fossil life on Mars. The pinkish deposits in Candor Chasm (enhanced color version PIA00155) may be due to hydrothermal alterations and the production of crystalline ferric oxides (Geissler et al., 1993, Icarus 106, 380). Viking Orbiter Picture Numbers 279B02 (violet), 279B10 (green), and 279B12 (red) at 240 m/pixel resolution. Picture width is 2231 km. North is 47 degrees clockwise from top.
