Yosemite National Park in California, United States, is renowned for its granite walls, dramatic waterfalls and striking light, all of which have inspired generations of artists. One of its most intriguing sights is the Firefall, a term that refers to two distinct events in the park's history. For decades, visitors gathered at Glacier Point to watch an artificial Firefall, in which embers were pushed off the cliff in a glowing stream of fire.
