It all depends on what the definition of "cloud" is...

Good to know, this will come handy the next time I'll fly in the
mountains. No danger to enter a cumulus, as a cumulus is clearly a cloud
and as such, by definition, not in contact with the earth. So there
can't be a mountain inside.


LOL... well, the problem will only develop when the cumulus was not formed
TOTALLY by classic cumulo-forming-bubble-rising mechanisms. Like, lets say
there is a little bit of upslope flow involved, and the other side of your
CU is flat against the 45-degree terrain which IS the "upslope". The trees
on that slope on the other side of the CU are, technically, in fog, but you
won't know that.....or care very much, in just a few minutes.....
