As we approached the first rappel our breath froze to our glasses and eyelashes. Our 2 liter water bladder was half frozen within 90 minutes, and while still inside of Steph's pack.
The only rappel was very fun, and seemingly endless. The canyon was longer than we anticipated, and contained a few more obstacles that we imagined. None were particularly difficult, but they kept the canyon interesting. We moved at a snail's pace and were done in about 4 hours. Arscenic would be much prettier with a little better lighting (during the summer).
Frozen platypus, 90 minutes into the hike.
