The single deadliest landslide in United States history

On March 22, 2014 at 10:37am, the SR530, or "Oso", slide engulfed the community around Steelhead Haven. The mud and debris from the adjacent mountainside destroyed 49 homes and ended the lives of 43 people. Community members immediately responded, bringing excavation equipment and shovels to help with the search and rescue effort. At times they were digging with their hands. Those who came were there to help, to find survivors, and later to recover friends and loved ones. As the response extended, those involved became determined to bring as much comfort to those who lost family and they did not stop searching until July 22, when the last of the 43 victims was recovered.

The response was massive

More than 900 local, state, tribal, and federal responders worked alongside, trained and untrained volunteers, families, and neighbors who came to help with the search, rescue, and recovery operations. People worked together while fighting cold weather, rain, quicksand-like mud and large areas already inundated with water. Learn more from stories of first responders and volunteers.

The community bonded together

Families were grieving the loss of loved ones. There was widespread loss of personal property, the inability to commute to work, and businesses lost access to their employees, customers, and supplies. Learn more from stories of community members and volunteers.

The extent of the disaster

The mud, soil and rock debris left from the mudslide covered an area 1,500 ft long, 4,400 ft wide and deposited debris 30 to 70 ft deep. The overall size of the Oso Landslide was approximately 270 million cubic feet. Two years after the mudslide, about 11,000 tons of wreckage had been removed from the slide area.

The Current State

Project and Planning

Shortly following the March 22, 2014 mudslide, discussions began circulating about creation of a memorial to commemorate the Oso mudslide. The intent of the memorial was to remember the lives of the 43 individuals who lost their lives, recognize the unprecedented response effort that followed the event, honor the community that was lost and provide information about the slide itself.

As families and the community have coped with grief, and the landscape has slowly begun to heal, calls for a memorial have become louder and steps are being taken to create a space at the site for gathering, learning, grieving and comforting. Learn more about the project here.
