      Dory - thanks for the question. Crater Lake is really clear, yes. I've known the park's biologist, Mark Buktenica, for years, and he's the expert on this . . . but what I know is that the lake's isolation from stream input (just snow and snowmelt on the surrounding caldera) mean that no organic material or sediment come in to foul the water. What I see in the water mostly is pollen from the trees - quite a lot, really, in certain seasons.

      Viz can be as good as 130 feet vertically from the surface, and that's as good as I've seen in clear ocean water like the Seychelles.

      What's also fascinating is that there is no surface outlet, no river coming out of the lake. To simplify, its level is a balance between precip and runoff in, and underground seepage out.

      -Bryan

      So what's Crater Lake like? I hear it's really clear.

      Just curious as to the word 'imperability' in your signature. Can't find a definition, and Google searches show it in the search blurbs. But it doesn't show up in the various articles that the blurbs belong to. As far as i can figure out from the usage in the blurbs, it means impermeable to gasses. Apparently, the root for the closest word, is the Latin 'impero', meaning, to command. From your screen name, I'm guessing you're on a them edumicated folks. Just wondering if you would send me a link to the definition.

      Thanks, PP

    Dive History:
    Three-quarters of my dives have been cold and drysuited, diving mostly on the left coast from San Diego to Port Hardy. My all-time best warm-water dives were in Madagascar and the Seychelles, diving with a shark researcher. My favorite cold-water sites are off Vancouver Island, from Nanaimo to God's Pocket.
    .
    Certification History:
    My OWD checkouts were conducted in two local Oregon rivers. I was startled, years later, to review my divelog and find a 58-minute dive among those training dives. Cold water, too. Bought a drysuit after dive eleven, being a bear of spare frame (but not of little brain).

    At the urging of my instructors, and not without misgivings, I gained SSI pro ratings including Adapted (aka Disabled) Diving Instructor, Dive Control Specialist Instructor, and Master Instructor.

    My tech certs are through TDI, and at the end of 2014 I crossed over to become an SDI and TDI Instructor. After a long SI for lumbar procedures I am back, baby!
