Round Top Sunset..

Caught this reflection in the water tank while walking the dogs in the Sibley Volcanic Regional Preserve. (http://www.ebparks.org/parks/sibley)

Round Top, one of the area's highest peaks, is made up of lava and volcanic debris left over from a 10-million-year-old volcano. During the past 10 million years, massive tectonic forces on the Hayward and Moraga earthquake faults uplifted the Berkeley hills, folding bedrock formations and tilting the Round Top volcano complex on its side.
