It one of the few remaining fossil fish localities that has not been either destroyed or made inaccessible due to urban  development. Shown is one of several slabs of diatomaceous sandstone with abundant fossil fish (perhaps a species of herring) collected in the 1970s from the area now underneath the Mulholland Estates security gate/access road. Many hundreds if not thousands of these 5 1/2 inch fish must have encountered an area of low oxygen content and all died at once.
