Yosemite National Park, California , USA


This park was published as a national park in 1890.  It is world famous for its rugged terrain, waterfalls and century-old pine trees (Sequoia).  It covers 1200 sq km and the "fire" waterfall of El Capitan is one of the most spectacular of all the 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 February.  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 it's appearance depends on a few natural phenomenon's occurring at the same time, and just plain 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 be much snow left to melt.

2nd, is the specific angle of the sun's rays hitting the falling water.  The sun's position must be exactly at a particular spot in the sky.  This occurs 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 a darkened 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.  Usually permission has to be allowed to enter the park that time of year, as dangerous road conditions could be hazardous to travel.   

Someone did and we all get to see it.
