This picture, taken on 19 January 2004, shows the summit caldera (collapsed magma chamber) of the volcano Albor Tholus. It is of particular interest as the 3 km depth of the caldera approaches the height of the volcano, which is unusual on Earth. A bright "dust fall" seems to flow from the plateau into the caldera.
