Flood debris on Mars

Flood debris on Mars

Fig. 2.15 . A panorama of the surface of Mars taken from the Mars Pathfinder spacecraft soon after itsí landing on 4 July 1997. The scene is littered with boulders and rocks, the debris of catastrophic floods early in the planetís history. The flood residue is found between a few meters away from the lander to the two modest hills, the Twin Peaks, which are about 30 meters tall and located at a distance of about one kilometer. Between and partially covering the rocks is rust-red, iron-oxide dust, the result of chemical weathering of exposed rock surfaces here and elsewhere. (Courtesy of NASA/JPL.)
