Mitigating Hazards at Cascade Range Volcanoes
The 1980 eruption of Mount St. Helens was monumental in so many different ways. It had a huge impact on the geography of southwestern Washington, ash affected many people, lives were lost, and lessons were learned. The eruption also led to the creation of the USGS Cascades Volcano Observatory in Vancouver, Washington.

Eyes on Earth Episode 48 – Satellites and the Forest Census
Eyes on Earth Episode 48 – Satellites and the Forest CensusIt’s possible to map vegetation type with Landsat, but getting the maps right requires more than satellites alone. The teams behind LANDFIRE use an extensive network of ground control points to check their work, thereby bolstering the reliability and utility of their multi-layer GIS product suite.
