آبشار آتش در پارک ملی Yosemite آمریکا

Fire Waterfall at Yosemite National Park !!!






This park was gazetted as a national park in 1890. It is world famous for its rugged terrain, waterfall and century-old pine trees. It covers 1200 sq km and the "fire" waterfall of El Capitan is one of the most spectacular of all scenery.





The spectacular view of the waterfall is created by the reflection of sunlight hitting the falling water at a specific angle. This rare sight can only be seen at a 2-week period towards the end of Feburary. To photograph this rare event, photographers would often have to wait and endure years of patience in order to capture them. The reason is because its appearance depend on a few natural phenomenons occuring at the same time and luck.





1st, Is the formation of the waterfall - The water is formed by the melting of snow and ice at the top of the mountain. It melts between the month of December and January and by the end of February there might not have much snow left to melt.





2nd, is the specific angle of the sunray hitting the falling water - The sun's position must be exactly at a particular spot in the sky. This occur only in the month of February and at the short hours of dusk. If it is a day full of clouds or something blocking the sun, you can only take pictures of your own sorry faces on the waterfall. It coincides with the fact that the weather in the National Park at that time of the year is often volatile and unpredictable. It compounds to the difficulty of getting these pictures.

The Yosemite Firefall was a summer time ritual that lasted from 1872 until 1968 in which burning hot embers were dropped a height of about 3000 feet from the top of

Glacier Point in Yosemite National Park down to the valley below, and from a distance looked similar to a glowing water fall

because the people who dumped the embers made sure to do so in a uniform fashion.
