Subject: Narcosis at the Gil
I too have the experience of getting narked around 90 feet at Gilboa 
Quarry.  But from my experience it seems that the extremely long swims in 
the 39 degree water are major contributors to this situation.  Also, have 
you ever noticed that you can detect both narcosis and cold better when 
there isn't much to look at down there?  The walls are cool but not 
totally engaging to the mind.  I also get narked easily in the Great 
Lakes.  This past week I did the Arabia (around 95') and the Forest City 
(around 150') both in 38 degree water and yep, got narked.  Still I 
recall all the wonderful artifacts I saw.  The darker waters of Huron 
seem to make for a more depressed narcotic experience than something deep 
in clear waters.  But that may just be my personal attitude - low vis 
usually makes me feel more cautious and paranoid/narked too.  Caves are 
usually not so gloomy to me because the water is clear so the darkness 
gets easily dispelled by the old "neutraleak".

I was actually disappointed in the Arabia, after spending several summers 
diving in Superior, Huron/Tobermory was just a bit of a let down!! 
Spoiled rotten I guess :>

Going to do cave diving in Missouri in October - anyone else going?
