Mazatzal: the rock of sugar in approximate true colors - Sol 78

Caption NASA originale:"This approximate true-color image taken by the PanCam on the MER Spirit shows the rock dubbed Mazatzal before the Rover drilled into it with its RAT. On sol 82, Spirit ground into a circular patch of the rock called 'New York', then repeated this operation on sol 85 to complete the hole. Several observations were made during this grinding process with the Rover's suite of scientific instruments. Preliminary results suggest that fluid may have been present during Mazatzal's formation. Images from the PnCam's blue, green and red filters (480, 530 and 600-nanometer filters) were combined to make this picture".

Nota: se questo è il colore "approssimativamente vero" di Mazatzal e dei suoi dintorni (ergo anche del rim di Bonneville), allora dobbiamo chiederci come mai tutte le altre immagini in colori "approssimativamente veri" - sempre a detta della NASA - dell'Area di Gusaev sono così diverse (e neppure lontanamente parenti di questa, cromaticamente parlando).
