Nevada Falls is 594 feet tall and was gushing with water during our visit after a good snowfall year. This flow of water kicked up a huge mist in front of the falls and produced this brilliant spectrum.
Vernal and Nevada Falls are both in Little Yosemite Valley, which, like many of Yosemite's features, was carved out by glaciers.
Remember, it's not just a picture, it's a story.
