Extreme rainfall during two atmospheric river events in January 2021 and January 2022 triggered a series of debris flows in the Columbia River Gorge, Oregon. The flows had significant impacts, including multiple highway closures and one fatality.

This interactive geonarrative (Esri Storymap) highlights rainfall data and observations of debris flow deposits by the Oregon Department of Geology and Mineral Industries (DOGAMI) within the 2017 Eagle Creek burn area. The impact of the Eagle Creek Fire on debris-flow susceptibility is an ongoing area of research performed collaboratively between the USGS and DOGAMI.
