Saltland, in natural colors (1) - Sol 788

Caption NASA originale:"While driving Eastward toward the North-Western flank of McCool Hill, the wheels of NASA's MER Spirit churned up the largest amount of bright soil discovered so far in the Mission. This image from Spirit's PanCam, taken on Sol 788 (such as March 22, 2006), shows the strikingly bright tone and large extent of the materials uncovered.
Several days earlier, Spirit's wheels unearthed a small patch of light-toned material informally named Tyrone. In images from Spirit's PanCam, Tyrone strongly resembled both Arad and Paso Robles, two patches of light-toned soils discovered earlier in the Mission.
Spirit found Paso Robles in 2005 while climbing Cumberland Ridge on the Western slope of Husband Hill. In early January 2006, Spirit discovered Arad on the basin floor just South of Husband Hill. Spirit's instruments confirmed that those soils had a salty chemistry dominated by iron-bearing sulphates".
