Be prepared for bugs and bears. We took out last week and it was an interesting trip. The Mosquitos got a few people really bad first the of couple days. Use bug spray with Deet, mine went fast when I had to share because the hippy stuff others brought didn't work at all. I faired pretty well with pants and a long sleeve shirt treated with permethrin but my legs got hammered in ten minutes before I put my pants on at the first camp. When the Mosquitos died down the biting flies came out. We had two bear sightings and a bat bite. It is berry season as we seen berries on the bushes and berry filled scat.
The river was at a great level, we did scout Joe Hutch Canyon but my line was pretty easy and dry. I took the right side of the tounge setting me up to split the two holes near top/middle of rapid and hit a big wave nicely before pulling to stay off the wall. Everything else was straight forward read and run. The best hits of the trip came at a hole center right just above the first bend, near the top of Coal Creek Rapid. That was our groups favorite rapid of the trip.
Have fun and keep a clean camp. Also check out the Alert - bears on desolation canyon thread.
