The time-lapse duo that took us on a journey to Dry Tortugas and Death Valley are back at it again with a spectacular look at America's oldest national park — Yellowstone.

The SKYGLOW project, a crowdfunded visual endeavor by Harun Mehmedinovic and Gavin Heffernan, kicked off a couple years ago with the mission of exploring "the effects and dangers of urban light pollution in contrast with some of the most incredible dark sky areas in North America." Since then, we've been treated to some of the most trippy views of our nation's parks and urban skylines.

In "Hades Exhales," viewers are given a day-to-night tour of one of the most volatile geothermal landscapes in the country. The explosive, boiling power of Yellowstone's geysers, mudpots and hot springs are further complemented by the prismatic color palette of the microbial mats that thrive along the edges of these features. The starry time-lapse is a unique view of a place that is photographed frequently by tourists.

In addition to bringing attention to the environmental effects of light pollution, the SKYGLOW team dedicated the video to Colin Nathaniel Scott, a 23-year-old man who died tragically in Yellowstone after straying from the boardwalk and falling into one of the hot springs in June. His death occurred mere days after filming for "Hades Exhales" wrapped.

"Yellowstone provides the visitors a spectacle of geothermal features and prismatic colors as pressure underneath builds to eventual geyser explosions across the basin," Mehmedinovic writes. "This breathtaking volcanic ritual serves as reminder that some of the most beautiful parts of nature are often the most dangerous."
