In Yosemite National Park, on the eastern slope of Mount El Capitan, there is a 650-meter waterfall. For most of the year, it is unremarkable, but in February, falling water flows turn into “lava flows”. An amazing natural phenomenon is due to the fact that at sunset the sun’s rays are reflected in a waterfall, creating a visual illusion that hot metal is flowing from a rock. According to legend, on the top of the mountain was the house of a blacksmith who made the best horseshoes for horses in the area. But due to heavy rain, the forge was washed off the cliff. Since then, the waterfall once a year “reminds” of this tragic event.
