Other Cascades Volcanoes

Metropolitan Portland, Oregon, like Auckland, New Zealand, includes most of a Plio-Pleistocene volcanic field. The Boring Lava includes at least 32 and possibly 50 cinder cones and small shield volcanoes.  Wood, C.A., and Kienle, Jurgen, eds., 1990,...
Although Mount Rainier (Washington) has not produced a significant eruption in the past 500 years, it is potentially the most dangerous volcano in the Cascade Range because of its great height, frequent earthquakes, active hydrothermal system, and...
Eruptions in the Cascades have occurred at an average rate of 1-2 per century during the last 4000 years, and future eruptions are certain. Cascade Volcano Observatory, 1994, Preparing for The Next Eruption in the Cascades: USGS Open-File Report 94-585.
During the past 10,000 years, about 60 giant debris flows from Mount Rainier have filled river valleys to a depth of hundreds of feet near the volcano, and have buried the land surface under many feet of mud and rock sixty miles downstream. Seven debris...
Eruptions of Mount Rainier usually produce much less volcanic ash than do eruptions at Mount St. Helens. However, owing to the volcano's great height and widespread cover of snow and glacier ice, eruption-triggered debris flows at Mount Rainier are...
The major peaks in the US part of the Cascade Range are (from north to south) Mount Baker, Glacier Peak, Mount Rainier, Mount St. Helens, Mount Hood, Mount Adams, Mount Jefferson, Three Sisters, Newberry Volcano, Crater Lake, Mount McLoughlin, Medicine...
Several lofty volcanic peaks dominate the Cascade Range of the Pacific Northwest; the principal part of the range extends from Mount Garibaldi in British Columbia, Canada, to Lassen Peak in northern California, a distance of about 1000 miles.  Sources of...
Debris flows pose the greatest hazard to people near Mount Rainier. A debris flow is a mixture of mud and rock debris that looks and behaves like flowing concrete. Giant debris flows sometimes develop when large masses of weak, water-saturated rock slide...
Mount Rainier, in Washington State, is the tallest (4,392 meters, 14,410 feet) volcano in the Cascade Range but it is only the third most voluminous volcano after Mounts Shasta and Adams. Source: Swanson, D.A., Cameron, K.A., Evarts, R.C., Pringle, P.T...
The Three Sisters area (Oregon) contains 5 large volcanic cones of Quaternary age-- North Sister, Middle Sister, South Sister, Broken Top, and Mount Bachelor. The ages of most volcanoes in the Three Sisters area are not precisely known. North Sister, a...
