Our club did it's annual camp and dive at Pavilion Lake last weekend and I took along some of my vintage kit. I dove St72's and a twin 40cuft rig, Hawaiian pack, simple webbing harness, J valves, horse collar single hose and doublehose.
It was a lot of fun observing Microbiolites (calcified bacterial colonies dating 10,000 years+), fish, calcified rocks and logs and very good vis. Both dives I did with the thin wetsuit went below the thermoclines into 46F water but I'm Canadian so it was like bath night back on the prairies
