The California Historic Landmark 83 in San Francisco contains two shoreline markers, one of which is located on the corner of Market Street and First Street. Look for the plaque on the southwest corner of the intersection that marks where the shoreline was in 1848. If you’re standing on or around the plaque and facing down Market Street towards the Ferry Building, everything from that point on is built on top of landfill or sunken ships. The other shoreline marker is located north on First Street on the corner of Market Street, Battery Street, and Bush Street.
