In a beautiful time-lapse video recently released by the two photographers behind Skyglow project, a book and video series exploring the effects of light pollution, we see a fog roll into the Grand Canyon like an ocean wave and the Colorado River disappear.
It’s called a full cloud inversion and is caused by cold air trapped inside the canyon being covered by a layer of warm air. The weather phenomenon is so rare that it took years to capture the footage.
In an interview with BuzzFeed News, Harun Mehmedinovic explained how the project came together and the explosive final frame of the video.
America’s national parks include some of the most cherished natural landscapes and cultural sites in the world. Today is World Heritage Day and we’re recognizing a unique park with a global profile. Hawai’i Volcanoes National Park is one of the few places on Earth where visitors can safely get an upclose look at an active volcano. Witness powerful natural forces at work as Kīlauea and Mauna Loa (two of the world’s most active volcanoes) continue to add land to the island of Hawaiʻi. Photo by Janice Wei, National Park Service.
