Yellowstone – Rainbows at Old Faithful

The vapor of Old Faithful’s eruption at Yellowstone and a bright sun form a rainbow further beautifying the world famous geyser. There is an illusion of two rainbows in the first image – one in the geyser and another one against the blue sky.

Old Faithful at Yellowstone

Discovered in 1870 by the Washburn Expedition,¬†Old Faithful¬†geyser was named for its frequent and somewhat predictable eruptions, which number more than a million since Yellowstone became the world’s first national park in 1872. Old Faithful can vary in height from 100-180 feet with an average near 130-140 feet. Eruptions normally last between 1.5 to 5 minutes.
