WASHINGTON (CIRCA) — California's Yosemite National Park did not suddenly develop a volcano, but this phenomenon sure makes it seem that way.
Firefall is the remarkable effect that happens to Horsetail Fall in Yosemite Valley during mid- to late February each year.
"This unique lighting effect happens only on evenings with a clear sky when the waterfall is flowing," the National Park Service reports. Anything from how much water is falling to a slight haze can alter the way the waterfall looks.

Nature photographer Vaché Geyoghlian posted his images of this year's firefall on Instagram.
The phenomenon is expected to happen again until this weekend. Then, visitors will have to wait until February 2020 to see it again.
