    • Ground-Based lidar Data of a Section of the Point Bonita Lighthouse Trail, Golden Gate National Recreation Area, Marin County, California, January 23, 2025

    Metadata Updated: September 14, 2025

    A rockfall occurred between the night of January 5 and the morning of January 6, 2025 on the Point Bonita Trail in the National Park Service Golden Gate National Recreation Area, California. The rockfall originated from a granodiorite rock face in the Franciscan Formation and deposited approximately 25 cubic meters of rock on the pedestrian trail below. The U.S. Geological Survey collected three three-dimensional point cloud models of the rockfall and surrounding terrain using GPS and terrestrial LIDAR instruments. The three surveys were performed at various distances and angles from the rockfall to best capture its dimensions given limited access on the surrounding trail.
