Strange Title I know . . . .
You see, Mt. Shasta is home to the ancient race of
highly advanced beings called the Lemurians. The Lemurians
lost their homeland at the time Atlantis sank into the sea,
and they constructed a huge city inside of Mt. Shasta. Disguised
as lenticular clouds, their spaceships dock
on the peak to load and unload passengers.

Although not uncommon on Mt. Shasta, lenticular clouds seem to
typically form when other types of clouds are not abundant or even present
at all. We typically have a clear day except for the 'pancakes'. This
morning was a little different in that I glimpsed this lenticular
forming through normal cumulus clouds.

Taken during the challenge . . . but alas, I'm out of slots in
the eligible. :)
