The Emeryville Shellmound, in Emeryville, California, is a once-massive archaeological shell midden deposit (dark, highly organic soil containing a high concentration of human food waste remains, including shellfish). It was one of a complex of five or six mounds along the mouth of the perennial Temescal Creek, on the east shore of San Francisco Bay between Oakland and Berkeley.
