Just got off Cat this morning.
I started at Potash, and there were tons of great sandbar beach camps before the Confluence.
If you have the new rivermaps book, the Lake Powell camps at Gypsum, Above Easter Pasture, New Face Rockfall, Fallen Slab, and Rock Fall are all in good shape. I don't remember if the across from Dark Canyon or Cove Canyon sites were good - I was too busy relaxing in the bits of shade there to pay any attention to those camps. There is nothing after the Rock Fall camp just before Dark Canyon. I had planned on camping at Mille Crag as I had done years ago, but it was such a mucky mess that I just rowed to the takeout instead.
There are two more rapids than are shown on the rivermaps book - both are easy read and run.
Dirty Devil ramp is in the best shape i've ever seen it.
The current was fast until just before Cove Canyon, slowed down quite a bit by Dark Canyon, and was mostly gone just after Mille Crag Bend. I got lucky with zero wind and rowed from Big Drop Beach to the takeout in a very long day.
