Host Dave Schlom spends time on one of his favorite topics, California's volcanoes, with two United States Geological Survey staff members from the USGS California Volcano Observatory based at Moffett Field in the San Francisco Bay Area.
Jessica Ball is a USGS Volcano Hazards and Communications Specialist and Alicia Hotovec-Ellis is a seismologist and monitoring expert.
Both join Dave for a tour of California's volcanoes from the border of Mexico at the Salton Trough to Mt. Shasta near the Oregon border. Volcanoes dot the Golden State's landscape and create some of the most interesting and beautiful landscapes in the west.
Before Mt. St. Helens erupted in 1980, Northern California's Lassen Peak was the last volcano to erupt in the contiguous United States with a series of eruptions from 1914-1917 that led to the creation of Lassen Volcanic National Park.
