In the Cascade Mountain range-
Oregon’s Mount Hood… slumbers peacefully as sheer blankets of evening mist and sunset clouds drift over in muted shades and shadows.
In Northern California, Mount Shasta and her companion, Shastina, appear to float without a stir above the the remnants of a catastrophic landslide that occurred 350,000 years ago when an ancient volcano collapsed to form the Shasta Valley.
Mount Baker, the highest peak in the North Cascades of Washington State, keeps watch as outrigger fishing boats trawl along the waters of the Puget Sound. She is the youngest in a volcanic belt that has been recurrently active for the past 1.3 million years.
Mount St. Helens, also a youthful volcano in the Washington State Cascades, changed her appearance dramatically exactly thirty-five years ago. May 18, 1980, an eruption blew off the upper 1,300 feet of the summit and created a 1.2 x.2.2 mile horseshoe-shaped crater. Her flat-topped peak stands as a testament to the “Forces of Nature.”
USGS geologists consider the eruption potential for the first three sleeping giant to be “High.” Monitoring of seismic activity is important because of the manner in which these particular volcanoes erupt and their proximity to large population centers. Mount Hood last erupted in 1865; Mount Shasta 200-300 years ago; Mount Baker 6,700 years ago- and counting!
