California Historical Landmarks in Alameda County
California Historical Landmark 335
Shell Mound Site
Owned By Bay Street Emeryville
Southeast Corner of Shellmound Street and Ohlone Way
It is said that the Indians who came to this site camped just above the shoreline. The shells they threw aside from their catches of shellfish eventually covered some hundreds of thousands of square feet, marked by several cones. When the University of California excavated this site in the 1920s, they found that the mound consisted mostly of clam, mussel, and oyster shells, with a plentiful mixture of cockleshells.
