the end of the shutter ridge in the Rockridge district of Oakland, where it joins the north fork (Claremont Creek) at approximately the intersection of Forrest Street and Miles Avenue. A small section of above-ground creek exists as the Rockridge-Temescal Greenbelt parallel to Claremont Avenue between the Grove Shafter Freeway and Telegraph Avenue. A pumping station at the top of the greenbelt diverts water from the tunnel and pumps it up to the surface creek. After Telegraph Avenue the tunnel continues east underneath the Temescal Community Garden and Temescal Creek Parks, then follows 53rd Street through Emeryville to its mouth at Bay Street. Mouth area Temescal Creek is a perennial stream, and as such, was highly valued by early settlers. At its mouth, the indigenous Ohlone people (Chochen/Huichin band), and their predecessors, built up the shellmound of Emeryville, the largest and most studied shellmound on the shoreline of San Francisco Bay. When the area was part of the Peralta's Rancho San Antonio, the site near the shellmound was one of the landings for the ranch where their cattle and hides were loaded for shipping. Cattle and other livestock were slaughtered in this vicinity right up through the early 20th century for various meatpacking plants in an area which became known as "Butchertown". It is believed that Temescal Creek once supported a population of rainbow trout, though urbanization and the damming at Lake Temescal have led to their decline. Archeological evidence indicates that coho salmon were also likely found at one time in the creek. The Emeryville Shellmound is also notable for its remains of beaver (Castor canadensis). Today, the creek is mostly underground in culverts in the flatlands, but many stretches are open above Lake Temescal. In 2000, a segment of the creek below the tracks of the Union Pacific Railroad in Emeryville became accessible to the public after the demolition of one of the buildings of the historic Sherwin-Williams paint factory in early 2000. Temescal Creek now flows in an open culvert through the 2002 Bay Street Mall development. This is just about the spot where the Emeryville Shellmound once stood. A small informational park commemorating the creek and the Ohlone presence at the site is situated here. At Shellmound Street, which runs approximately along the original Bay shoreline, the creek returns to a culvert which takes it to San Francisco Bay. This straight course, however, is a later
