In seeking a location to shoot the sunset upon Mt. Diablo I turned to see these incredible nebula like cloud formations above me. I moved my location to include the twisted and complex branches of a gnarly California Oak near the top of the hill. The clouds, lit by the setting sun, made a great backdrop with the intricate branches of the old oak in silhouette. These California Oak trees are found all over the foothills of California from the coast to the Sierra Nevada and make for wonderful subjects during the winter and spring months.
