I'm looking for any tip's,thought's, general info on high altitude dives. The location is Lake Tahoe, Northern California- elevation 6229ft the water is beautiful, well over 100ft vis. I've done some modest rec dives there, but am thinking of setting up a line and doing a bit of CWF this summer, want to learn a bit more before taking the deeper plunge-----how much will the up in red blood cells offset lack of oxygen, should breathup be altered, risks, benefits, etc.
