Although rare, full cloud conversions are something we know well here, covering the same phenomena over the last few years both here and here. This particular timelapse video by filmmaker Harun Mehmedinovic captures how beautifully the descending clouds imitate waves when trapped within the Grand Canyon, undulating against the uppermost edges of the natural wonder’s deep valley.
The video was filmed as a part of SKYGLOW, a crowdfunded project that seeks to explore the effects of urban light pollution by examining some of the darkest skies across North America. You can see breathtaking stills from the video, which originally premiered on BBC Earth, below. (via PetaPixel)
