Rainbow Falls, Devil`s Post-pile National Monument Stock Photo

A sunny, summer`s afternoon at the Rainbow Falls on the San Joaquin River in California, USA. Steep cliffs of basalt rock walls enclose the 102` foot falls which plunge into the misty pool below. The constant mist generates rainbows on most days, the reason for the name and a reward for the hikers who make it to the end of the is trail through Devil`s Post-Pile National Monument near Mammoth Lakes, California. Some people hike to climb down to swim in the pool at the bottom.
