These reports are longer than the 2-page abstracts seen from the Lunar
and Planetary Science Conference, some over 30 pages long.

A great image of dense fog in Valles Marineris is shown in this
report:

And this report has a beautiful full-color image of this very dense
fog:

Adsorption water driven processes on Mars.

This article speculates on how adsorbed layers of water might be used
by microbes on Mars.

Valles Marineris is both low altitude and low latitude so should be
within the pressure and temperature range to permit liquid water for
this fog close to the surface.
