The Cascade volcanoes have had more than 100 eruptions over the past few thousand years, many of them explosive eruptions. [21] However, certain Cascade volcanoes can be dormant for hundreds or thousands of years between eruptions, and therefore the great risk caused by volcanic activity in the regions is not always readily apparent.
This is a list of Cascade volcanoes, i.e. volcanoes formed as a result of subduction along the Cascadia subduction zone in the Pacific Northwest of North America. The volcanoes are listed from north to south, by province or state: British Columbia , Washington , Oregon , and California .
The High Cascades are the most recent volcanic arc in the Pacific Northwest, which forms the Cascade Volcanoes. These volcanoes, including the Three Sisters, were fed by magma chambers resulting from the subduction of the Juan de Fuca tectonic plate under the western edge of the North American tectonic plate.

In today's puzzle, there are eight theme words to find (including the spangram). Hint: The first one can be found in the top-half of the board. Here are the first two letters for each word:
The area can be hiked, and can be accessed by roads in the Gifford Pinchot National Forest. One of 13 volcanic cones in the West Crater-Soda Peaks zone, which covers an area of 39 square miles (100 km 2 ), West Crater is part of a monogenetic volcanic field with basaltic to andesitic volcanic edifices that vary from 360,000 years old to 2,000 ...
The Cascade Volcanic Arc is a chain of volcanoes stretching from southern British Columbia down to northern California. Within the arc there is a variety of stratovolcanoes like Mount Rainier and broad shield volcanoes like Medicine Lake. But calderas are very rare in the Cascades, with very few forming over the 39 million [1] year lifespan of ...
It is now the site of multiple volcanoes that have been active for 39,000 years, many of which lie underwater. It’s also populated with villas, small villages and shopping malls and home to ...
It is a major preserved stratovolcano in the Pemberton Volcanic Belt, an extinct portion of the Canadian Cascade Arc. [1] Mount Baker (Near the United States-Canada border) — highest peak in northern Washington. It is an active volcano. [2] Steam activity from its crater occurs relatively frequently. Mount Baker is one of the snowiest places ...
