The Oso Landslide in Snohomish County, Washington, is among the most significant geologic disasters in recent U. S. history. The landslide occurred on a valley slope with documented history of intermittent landslide movement dating back to the 1940s; recent slope movement in 2006 blocked the North Fork of the Stillaguamish River and caused shallow flood damage to some of the nearby homes. The Oso Landslide is one of many landslides that have occurred on valley slopes above the North Fork of the Stillaguamish River.

The 22 March 2014 Oso Landslide became a rapidly moving, unchannelized debris flow that spread out as it travelled about 1 km across the valley, damming the North Fork of the Stillaguamish River, destroying and carrying away about 50 homes, taking the lives of 43 people, and burying about 1.5 km of State Highway 530.

Recent geomorphological research on landslides in the vicinity of Oso published in February 2016 Geology is based on radiocarbon dates. Ongoing research by the author uses radar rainfall to document variability in local intensity that may have been important as a triggering mechanism for the 22 March 2014 Oso Landslide.
