Horsetail Fall

Horsetail Fall in Yosemite is a small ephemeral fall on the east shoulder of El Capitan. If it is too cold in late Feb or early March, it won't flow, but if there is a good snowfall, followed by a warm day or two, it will start flowing. The sun sets just at the right angle this time of year to back light the fall. This phenomena attracts dozens of photographers every year. It was first photographed by Galen Rowell in the early 1970's.
