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 ??sfirefall??? draws scores of photographers to the spot, which flows down the granite face of the park???s famed rock formation, El Capitan.
