Here's the last one.  I was thinking about you all while we were on our trip, and took this one specifically for this forum thread!  :)  This is Picture Gorge, Oregon, in the John Day Fossil Beds. 

 Look for the red car for a sense of scale.

Sorry I haven't been around ... but Forum threads weren't high on my list while we were driving around the country!  We did 5300 miles, and I haven't figured out yet how many photos I took.  I've been through this thread now that we're back, and thoroughly enjoyed it!  :)
