The climb back over Half Moon Pass was tough. If you ever plan to do this hike, you'll need plenty of water so there's some left for that final climb. I took 3.5 liters and drank every drop. The view east from the pass looked very different with the sun behind me, than it had in the morning. A mile from the car I had the pleasure of meeting Senator and Mrs. John Glenn, out for an afternoon hike. I was back at the car by 5:15; a 10 hour round trip.
