As far as natural phenomenons go, it is one of the most spectacular.
These images capture the moment a waterfall in Yosemite National Park turns into a beautiful fountain of colour.
A rainbow forms in the spray emitted by the California waterfall, creating a dazzling effect.
The natural wonder was captured by photographer Justin Lee, who was overjoyed to find himself in exactly the right place at the right time.
Mr Lee, from British Columbia, Canada, was standing close to a cliff at the Tunnel View lookout when he spotted the colourful scene.
