In 2017, the massive Mud Creek landslide buried a quarter-mile of the famous coastal route, California’s Highway 1, with rocks and dirt more than 65 feet deep. USGS monitors erosion along the landslide-prone cliffs of Big Sur, collecting aerial photos frequently throughout the year.

Josh Logan, a physical scientist at the USGS Pacific Coastal and Marine Science Center in Santa Cruz, California, operates an unmanned aerial system, or UAS, often called a "drone", that is equipped with a video camera.

USGS provides the data to Caltrans, the California Department of Transportation, whose heavy equipment and earth movers are shown here.

USGS scientists continue to monitor the slide by collecting imagery every couple of weeks, weather permitting. Pilot Bob Van Wagenen, contracted through the Department of the Interior’s Office of Aviation Services, takes air photos for Jon Warrick’s Big Sur Landslide team, flying out of the Watsonville Municipal Airport in a Cessna 182R.
