A stunning time-lapse video of the Grand Canyon shows the carved formation as it may have looked millennia ago — but instead of water, it’s filled with what has the appearance of an ocean of fog.
Filmmaker Harun Mehmedinovic has set up his camera at the canyon 30 different times since 2015. During one visit, he managed to witness and film the dramatic changes of a full cloud inversion, which occurs when warm air traps cold air beneath and creates a sea of fog. The inversion lasted the entire day, allowing time for Mehmedinovic to film fog “crashing” on the “shores” of the canyon and swirling through winding passages.
The film made its debut on BBC Earth in early May and has been viewed online millions of times.
Mehmedinovic is a Bosnian-American who went into hiding in his war-wracked hometown of Sarajevo for three years when he was 9. His family stayed indoors in a cellar of their home to escape the Serbs. He moved to the U.S. when he was 13 and went to film school in Los Angeles.
