Owyhee cover photos for GSA Bulletin?

Our research group is finally getting our big paper about the Owyhee River finished (I am getting close with the map as well). I am hoping to snag the cover of GSA Bulletin with one of these photos. Any thoughts on the best? I like them all, of course, and some are true favorites...so be kind if you want to chime in. Want to narrow the field to 3 photos.
