Haystack Landing is a historic property in Sonoma County, California, now owned by Dutra Materials. Haystack Landing was a passenger and intermodal transport connection to San Francisco Bay via the Petaluma River and San Pablo Bay. The landing is currently the site of a historic steamer dock, a railroad bridge, and of a planned asphalt production and storage facility. In conjunction with the production of a horror film, it has been occasionally called "the most haunted site in Sonoma County". Haystack Landing was featured in then-congressman Frank Riggs' election campaign in the 1996 California First Congressional District race, when his ties to the property drew criticism.
