Looks like a rock to me. It is the same color you see in the rock outcrop on
the crater walls. Acording to the nasa rover sites, they are considering the
posibility of excavating a few inches of dust with one of Opportunity's
wheels to see if the bedrock that is visible is present elsewhere. Maybe
this same feature made them think that...
