世界奇观：美国加州惊现“火瀑布”

（单词翻译:单击）

 　　These amazing images were taken at Horsetail Falls in Yosemite National Park, California by wildlife photographer Penny Adams. For just a few days each year the sun sets over the falls creating a vivid red amber¹ glow - leading it to be re-named Yosemite Firefall. Ironically Horsetail Falls was a real 'firefall' in the 1870s when a hotel proprietor² began a night time show for visitors by pushing bark embers over the nearby Glacier³ Point Cliff, creating a waterfall of fire and sparks。
