This aerial photo taken May 22, 2017, shows a massive landslide along California's coastal Highway 1 that buried the road under a 40-foot layer of rock and dirt. A swath of the hillside gave way in an area called Mud Creek on May 20, covering about one-third of a mile of road and changing the Big Sur coastline. Photo by: John Madonna via AP
