The image shows a surface with at least two types of exposed bedrock, one that is light-toned and one that is dark. An enhanced color infrared image highlights these two exposures in yellows and blues, which such colors representing altered and unaltered surfaces, respectively.
The overlying, rougher blueish-toned bedrock appears to have undergone the most extensive erosion, revealing the smoother, fractured yellowish-toned bedrock below. We see windblown (aeolian) bedforms across the image, possibly the culprit behind the erosive forces that have removed and uncovered the underlying yellowish-toned bedrock visible today.
