Lee's Ferry / Glen Canyon Paddling

[tinneyr]

I'm planning on paddling upstream from LF in a couple of weeks. Has anyone out there done this paddle? I hear the CFS is between 7k and 13K. All the pic's I've seen of the river makes it look doable. I've paddled down Black Canyon below Lake Mead before and the flow rate looks comparable. I'd like to do some exploring also and have read about the petroglyphs. Is there anything else that I shouldn't miss?

Thanks for any advice. Ric
