Is is a volcanic firefall? No, just a natural waterfall, lit in a spectacular fashion by a certain angle of the setting sun.
For a few weeks in late February, this is what the mountain shoulder of El Capitan looks like each evening. Lit at just the right angle, by the westering sun, the falls takes on brilliant hues of red, orange and yellow.
Hoping for plentiful water flow and good weather conditions, photographers come to Yosemite in California from afar to get pictures of this fascinating natural phenomenon.
This mountain is also a destination for rock climbers.
