Thanks, guys. Bryan, the cliff dwellings are pretty astonishing - it's fortunate that they're as well-preserved as they are. We didn't spend a lot of time in that area, so we didn't get closer than shown in that shot, but it would be fascinating to see them up close. cs1, I shot much of the time with an orange filter; I prefer it to a red most of the time, as it doesn't black out the foliage as badly. I also experimented with a green filter at a few points on the trip; I'm not sure exactly how I feel about those results yet - it's a much lower contrast look in that terrain, except when red rock formations featured prominently.
