It's been a long week. Take a moment — or even a minute! — to watch something beautiful.
Around the third week of February each year, Horsetail Fall lights up Yosemite National Park with a spectacle of orange and red. The phenomenon, which has taken on the decidedly majestic nickname "firefall," is an optical trick of the sunset when a host of conditions are just right.
If the waterfall is flowing with snowmelt, if Earth is aligned with the sun just so — as it is this time of year — and if the skies are clear enough to let that sunlight through, the fall appears to flare with the fiery glow of lava.
