Twin Peaks tower over 900 feet above San Francisco's geographic center and affords spectular panoramic views, especially on clear days. The 853-foot tall Transamerica Pyramid is partially obstructed in the upper left. The dome of City Hall is just below. Market Street bisects the view with the once tall Ferry Building at its head. The Bay Bridge is on the upper right and across the bay to the right the third steel is the 307-foot tall spire of the University of California Berkeley's campanile. With some 800,000 residents crammed into 47 square miles, finding nature in the City to photograph can be challenging so you have to know where to look.
