Closing-up on Mazatzal - Sol 77

Caption NASA originale:"This b/w PanCam image of the rock called Mazatzal (at the top of the image) was taken by the MER Spirit on Sol 77 (March 2, 2004). It reveals some interesting features on this future RAT target, including variants in tone, a "sugary surface" texture and scalloped areas where parts of the rock seem to have been worn away. Mazatzal's uniqueness is made even more obvious when it is compared to the more typical, basaltic rock in the lower right of the image".
