VIDEOS/PHOTOS: Ten years ago, the deadliest landslide in U.S. history struck the small town of Oso, Washington.
Forty-three people were killed on March 22, 2014, when the hillside above the Steelhead Haven neighborhood in Snohomish County collapsed, wiping out state Route 530, homes and cars.
It was a beautiful Saturday morning in the close-knit community of Oso when the hillside gave way.
The community had seen a record-breaking start to the year with twice the average rainfall falling in February and March. But on March 22, 2014, spring was in the air.
At 10:37 a.m., a landslide changed that community forever. A rain-soaked hillside near Oso collapsed, sending around 18 million tons of sand, till and clay into the community of Steelhead Haven, destroying more than 30 homes.
