Mud Creek landslide "pyramid rock" profile and shoreface erosion

A series of images show the height of the ground and how it changes over 17 days.

Detailed Description

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. By analyzing overlapping photos, they made precise maps of the slopes and calculated volumes of material lost or gained over time. The last slide in this animation shows the differences between the May 27 and June 13 photos, calculating the volume of land lost or gained.
