Slide Ranch is located in the North Central Coast region of California, within the Gulf of the Farallones National Marine Sanctuary and Golden Gate National Recreation Area.

Slide Ranch long term monitoring survey overview

The site is located at the base of a steeply sloped cliff that opens onto a cobble beach. Large boulders are scattered throughout the intertidal zone and into the deep water. Transects and plots are arrayed along the boulder beach. The site receives high wave action but there are many semi-protected areas among the large serpentine and greywacke boulders in the area.
