On March 22, 2014, a major landslide occurred near Oso, Washington. When a portion of a hillside collapsed, mud and debris cascaded across the North Fork of the Stillaguamish River and engulfed the Steelhead neighborhood of some 30 homes, killing at least 24 people and causing the disappearance of many more.
