For silt combat, I brought a 12 oz squirt bottle and some coffee filters. The basic idea is to fill the squirt bottle and put a coffee filter under the lid. That way, all your water will pass through the filter before entering the bottle you are going to iodine, but don't squeeze to hard or you will break the filter. This seemed to work some because I could see the dirt stuck in the filter. The other advantage is the fact that you don't have to dip your bottle in the river.
For those of you that are afraid of heights, this is NOT a hike for you. The Day three climb that Jason has in the trip report is pretty much a technical climb. Especially in packs. Most of the "climbs" that I have run into in the canyon have been in teh range of 15 feet. This climb was more along the lines of 50ft. we don't have pictures because I was not willing to remove one of my three points long enough to take it. If you are uncomfortable about heights, this section will take you a LONG time. DON'T try this hike in four days.
In my opinion, this was one of the coolest hikes that I have done in the canyon. I rank it right there with the Boucher-Hermit loop. Great Views, Cool Camp Sites, not crowded, and just enough out of the Ordinarys.
