EVERY FEBRUARY, THE light of the setting sun hits the waterfall at California’s Yosemite National Park in such a way that it looks like a cascade of molten lava.

The phenomenon known as “firefall” draws scores of photographers to the spot near Horsetail Fall.

It only flows in the winter or spring, when there is enough rain and snow.

The sun only lights up the waterfall for about two minutes at dusk for a few days in February, so capturing the sight is a challenge.

Many are taking to social media to post spectacular photographs of the glowing waterfall.
