A shaft of sunlight creates a glow near Horsetail Fall, in Yosemite National Park, Calif. Mother Nature is again putting on a show at California’s Yosemite National Park, where every February the setting sun draws a narrow sliver on a waterfall to make it glow like a cascade of molten lava. The phenomenon known as “firefall” draws scores of photographers to the spot, which flows down the granite face of the park’s famed rock formation, El Capitan.
