This gorgeous new video comes from Colin Delehanty and Sheldon Neill, who wrote on their Web site that they filmed it by visiting the park repeatedly over a 10-month span. They hiked more than 200 miles and filmed for about 45 days to produce the footage you see above. (Here’s a list of the locations they visited and the equipment they used.)

It’s a sequel to a similarly stunning time-lapse video they released in 2012. That video was a big hit online, getting played more than 4 million times and racking up more than 31,000 likes on Vimeo. You can watch the original here:
