Yosemite National Park approximately midway between Los Angeles and San Francisco.
The bridge across the Merced River is crowded every sunset with photographers hoping for good color on Half Dome. More often than not nothing unusual happens. This photograph shows a very rare situation. I have been going to Yosemite frequently for some forty years and this sky is the first of its kind I have seen.
A storm had just cleared as the sun was setting producing this unusually colorful sky.
