14 DAY TRIAL // The so-called firefall featured in the picture above is actually a mere waterfall observable on the eastern edge of El Capitan, a vertical rock formation located in the Yosemite National Park.
Those wishing to catch a glimpse of it can only do so during winter and early spring, seeing how the waterfall only forms once the region's snow coverage begins to melt. Sources explain that the waterfall gets its orange glow from whatever light happens to hit it at sunset.
It appears that the fireball is only noticeable during the second half of February each year, simply because it is precisely within this time frame that the sun sets at just the right angle needed in order to make this phenomenon manifest itself.
Furthermore, the waterfall only glows orange for about 10 minutes every time it appears, so those wishing to see it up close would do best to be on the lookout or risk missing it.
