Ah! An excellent point and well spotted.. I wonder what sort of

I would like to dive that lake just to see.. despite the risk or my

Either he was diving in a solid block of deep frozen ice or his
thermometer was not accurate...

With regards to pressure differences in the freezing point of water,
this web page has a calculator that will allow you to vary the
salinity and the pressure:

http://www.csgnetwork.com/h2ofreezecalc.html

At 120 ft, we're looking at 54.45 psi... Assuming a salinity of 0 PSU,
the freezing point would be 31.501F... For the water to be 30F at 120
ft, it would need a salinity of 15.4 PSU... Normal sea water has a
salinity of approxmiately 33-37 PSU...

At normal atmospheric pressures, the Great Salt Lake will freeze at
around 11.8F and the Dead Sea at -6F due to their considerably higher
PSU values...
