First time I did this canyon, which was combined with Keyhole was my first time in Zion (Sep 03). There was tons of water that day. Since then I've done it completely dry, and with some water. A nice canyon for everyone. A classic.
I did Pine Creek with the WMC. There was a big storm in Zion a week before and the canyon was full of water and flotsam. We were all covered in it by the end of the day. I didn’t bring my wetsuit and was pretty cold the whole time. It is a fun canyon but easier when it is dry.
