Peak runoff typically occurs in May or June, but then some waterfalls are completely dry by August. They are rejuvenated in late fall by storms.
When photographer Greg Harlow set himself up at Glacier Point in Yosemite National Park to capture the famous sunrise spreading over the Sierra Nevada Mountains, he instead was awestruck by another wondrous sight. As the first rays of light poured across the landscape, they also touched the spray coming off off Yosemite Falls.
This waterfall measures 2,435 feet high -- one of the world's tallest waterfalls. Yosemite Falls actually consists of Upper Yosemite Fall, the middle cascades and Lower Yosemite Fall.
As Greg observed the sunrise, his attention was temporarily distracted by the twinkling rainbow of light refracting off the water spray. The sunrise ended up making the entire waterfall appear as a spectacular cascading rainbow.
The high winds whipped up the spray making the view even more visibly stunning. The full spectrum of a rainbow poured down the face of the cliff.
At first, Greg noticed the red shade, then quickly the other colors emerged. It's such a visual treat for us to see!
This amazing footage was captured at California's Yosemite Falls. Others have been treated to similar sights including moonbows, lunar rainbows and spraybows, where moonlight refracts off the spray of water or the waterfall.
