Hi Paul,

Perhaps my point was unclear. My issue was with the proposed
scenario in which the liquid water would be prevented from
boiling off due to the presence of an overlying stagnant volume
of gas saturated with water vapor, which I find untenable. I do
not dispute the existence of water vapor clouds in the Martian
