Don’t let any apocalyptic theories fool you. The spectacle in Yosemite National Park where the waterfall appears to be spouting lava is only an illusion. Only in February does the right situation occur for the sun to perfectly illuminate the waterfall as it sets so that it actually looks as if molten lava is flowing over the granite rock instead of water. The phenomenon is so intriguing that professional photographers often flock to Yosemite at this time of year to try to catch that perfect moment. In reality, it is nothing but an illusion, but it sure looks cool.
