Drone footage of the Mud Creek Slide along Big Sur coast, California, on July 19, 2017

USGS drone footage shows the slide from many angles. It points out buried and unburied parts of Highway 1, as well as new roads built across the slide for monitoring purposes.

Text across the imagery:
The Mud Creek landslide on May 20, 2017 moved approximately 2 million cubic meters of material (enough to fill a 900-mile convoy of dump trucks!). It buried State Highway 1 more than 20 meters (65 feet) deep.

The slide added about 13 acres of new land to the coast. Between May 27 and June 26, the seaward edge of the slide retreated about 30 feet. New roads built by the California Department of Transportation help monitor and sample the slide. The USGS regularly collects imagery of the slide area to measure changes to ground elevation and the coastal environment.
