A few us did a run from Christopher Creek through Hell's Gate canyon in AZ last weekend. Back when Eddyflower was accessible, Tom and Christian had a nice write-up about Hell's Gate, but besides that, which currently is lost, I found information about the run extremely hard to find (fortunately in lieu of Eddyflower, we had Tom). Will try to add some photos as time permits - we didn't take a lot since we were trying to move fast.
I added some information to River Brain based on our run:
Tonto Creek - Hell's Gate Canyon - River Brain
I also added another account of Christopher Creek, even though there's already good info out there:

The contiguous stretch of Christopher Creek all the way through Hell's Gate to Gisela gives you around 30 miles of continuous pool drop creeking which easily justifies 3 days on the river. It's a pretty unique stretch.
