Michael Lyle over at Mars Exploration Rover Imagery has some pseudo-color images of the Opportunity trench at Meridiani Planum. These are way cool, check 'em out. image 1, image 2, image 3, image 4, image 5, image 6. I think that one and three are just awesome.
And this is a darned nice RHazcam image :-)
Oh, one more. This look over the rim of Opportunity's small crater shows that these plains were made for drivin'. I don't think she's gonna have a difficult time making tracks toward that large crater.
Also, Steve Squyres updated.
