A major landslide occurred near Oso, Washington, on March 22, 2014, when a portion of a hillside collapsed, sending mud and debris across the North Fork of the Stillaguamish River. The 1-square-mile (2.6-km2) slide damaged property and formed an earthen dam, blocking the river and causing a barrier lake to form. Landsat 8 acquired the January 18, 2014 and March 23, 2014 images above. The March 23rd image clearly shows the aftermath of the landslide.
