Grand Canyon Total Cloud Inversion: December 11, 2014 – by GrandCanyonNPS
One minute time-lapse video of the total cloud inversion that filled Grand Canyon on Thursday, December 11, 2014. There is no audio track.
The action that takes place in this 1 minute video would take 15 minutes in real time. In some ways it looks like ocean tides coming in and going out. NPS Video by Michael Quinn.
