The team of Ryan, Melissa, and Briony, who blog at The Martian Chronicles, have posted extensively on their week-long geology tour of northern Arizona, including excellent photos. The group was looking at terrestrial analogs to Martian geology, but found a lot more.
Plugs for their road log showed up at Highly Allochthonous and Chinleana, which is where I found out about it. [right, Grand Falls. Credit, Martian Chronicles]
