A Cloud is Born

"Orographic clouds are clouds that develop in response to the forced lifting of air by the earth's topography." Midday in mid-summer on the flank of a 7300 ft peak I noticed something I'd never seen before; wisps of white developing out of a clear and empty blue sky. These wisps grew in size and coalesced into clouds (which blew eastward and gradually dissipated and disappeared leaving the sky as empty and blue as it had been before). I noticed this happening several times and realized the clouds were all forming in the same place, several thousand feet above the the peak of the mountain I was camped on. I ran to get the camera. The video starts with a few wisps visible and follows a cloud's development.
