Sunlight on the underground lake evaporating the ice to form clouds

of the Moon? It might work if your brain ever did.
Tell us about the canals on Mars instead, Lowell believed in 'em.


Well, you don't need underground nuclear furnaces when any given point
on your surface faces the Sun for about half a month, and doesn't face
the Sun at all for the rest of the month. That's bound to create a small
temperature differential that may result in melting and refreezing. Of
course it depends on how far down the ice is, the further down it is,
the less the temperature differentials are going to be, thus making the
process slower.
