Mark and all, This really is a cool image. Thanks for bringing it to our attention. I'm guessing you might appreciate a serious reply or two.
On earth, this is immediately reminiscent of a weathered lahar fragment. Volcanic mudflows involving big blocks in an ashy matrix are almost universal in the sorts of volcanic environments for which Mars holds all the solar system records. Add some wind ablation to sculpt both the block and the matrix, and this image depicts the result. This scenario would benefit from some liquid (water?) but could be seen in a dry pyroclastic ash flow. There are other possibilities, but this seem an obvious first guess for Mars.
