Hollywood Beach in Port Angeles is one of those neat little pocket beaches that can form when sediment is trapped against an artificial headland - and which are pretty common in heavily modified shorelines. The beach is neither natural nor intentionally created. It just sort of happened and has evolved to become a neat recreational resource.
The original shoreline was located much farther to the south, nearer the base of the original bluff, but in the early 1900s the Port Angeles shoreline was filled outward and the original beach was buried, along with the remnants of the native village that once lay at the mouth of Ennis Creek.

The eastern part of the beach is covered in fine dark wood particles, although I don't know if this came from this location or floated in from elsewhere. Port Angeles Harbor has been in the wood products business for its' entire history and there are no shortage of possible sources of this kind of material.
