Jake Gittes (Jack Nicholson) following Hollis Mulwray (Darrell Zwerling) – Point Fermin Park, S. Gaffey Street at W. Paseo Del Mar, San Pedro, California
While trailing Mulwray, Gittes discovers that water is dumped into the sea at night – Sunken City, San Pedro, California. In 1929, the 600 block of Paseo Del Mar began slipping to the sea and the movement, measured up to 11 inches a day, continued until the mid-1930s. The houses were moved but the eastern section of Point Fermin Park was lost and the terrain is very unstable. The area is closed but can still be observed from Point Fermin Park at W. Paseo Del Mar and Gaffey Street.
Jake’s car is parked near Walker’s Cafe, 700 West Paseo Del Mar, San Pedro, California.
