August, 2022, airborne lidar survey of Mount St. Helens crater, upper North Fork Toutle River, and South Fork Toutle River

Metadata Updated: October 28, 2023

The lateral blast, debris avalanche, and lahars of the May 18th, 1980, eruption of Mount St. Helens, Washington, dramatically altered the surrounding landscape. Lava domes were extruded during the subsequent eruptive periods of 1980-1986 and 2004-2008. During 2022, U.S. Army Corps of Engineers contracted the acquisitions of airborne lidar surveys of Mount St. Helens crater and two primary drainages–upper North Fork Toutle River and South Fork Toutle River with GeoTerra, Inc. The U.S. Geological Survey generated a terrain dataset from the classified point cloud with supplied breaklines and modified lake hydro-flattening, then exported a single digital elevation model (DEM) of the ground surface (that is, 'bare earth'), including beneath forest cover. This USGS data release contains digital elevation and shaded relief data as 3-foot resolution raster datasets (2022dem.tif and 2022demhs.tif, respectively). This DEM can support a variety of earth science investigations.
