I think I understand your confusion, Craig. Yosemite’s Firefall was a manmade event created when burning embers were pushed off Glacier Point, a true sight to behold that ended in 1968. Yosemite’s “natural firefall” is Horsetail Fall, a natural event that happens on the side of El Capitan at sunset some nights in February. It’s often mistakenly labeled “Firefall” (even by Yosemite), but that designation can only go to the Glacier Point original.

There’s not been any firefalls in over 60 years and definitely not on the El Capitan side of the Valley, does Glacier Point ring a bell???
