The last Firefall was on Thursday, January 25, 1968. Since it was winter, no crowd was present. The cameras I owned in those days could not capture the image. The Firefall was a daily event that occurred in Yosemite Valley. Traffic stopped and so did everything else at 9 PM every night. It took an hour for the traffic to clear. It was a pollution problem for Yosemite National Park,
The Yosemite Firefall was a summer time event that began in 1872 and continued for almost a century, in which burning hot embers were spilled from the top of Glacier Point in Yosemite National Park to the valley 3,000 feet below. From a distance it appeared as a glowing waterfall. The owners of the Glacier Point Hotel conducted the firefall. History has it that David Curry, founder of Camp Curry, would stand at the base of the fall, and yell “Let the fire fall,” each night as a signal to start pushing the embers over.
Now to replicate the past artificial lighting has brought back the effect. It is a challenge for photo hobbyists. It is claimed that it is a natural phenomenon.
