The Emeryville mudflat sculptures were a series of found object structures along the San Francisco Bay shoreline of Emeryville, California, largely constructed from discarded materials found on-site such as driftwood. The mudflat sculptures were first erected in 1962 and received national attention by 1964; through the 1960s and 70s, anonymous, usually amateur artists would construct sculptures visible to traffic at the eastern end of the Bay Bridge. With the creation of the Emeryville Crescent State Marine Reserve in 1985 and increased attention to ecosystem preservation, the last mudflat sculptures were removed in 1997.
