March 24, 2004 — Mazatzal reveals some interesting features 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. Scientists will use Spirit's Rock Abrasion Tool to systematically peel back Mazatzal's layers and analyze what's underneath with the rover's Microscopic Imager, plus its Moessbauer and Alpha Particle X-ray spectrometers.
