What is the Cascade Range known for?
The Cascade Range is best known for its tall volcanoes and deep evergreen forests. While the North Cascades contain an extremeley rugged cluster of jagged peaks, it is the long line of snowy volcanic cones running from Mount Baker south to Lassen Peak that dominate the range for its entire length.
What is special about the Cascade Mountains?
The Cascade mountain range is named for waterfalls — hundreds of them, big and small, that cascade down streams and plunge over cliffs, carrying huge amounts of water from winter rains and melting snow. Probably the most famous, Multnomah Falls is located on the Oregon side of the Columbia River Gorge.
How did the Cascade Range from?
Along its Oregon segment, the Cascade Range is almost entirely volcanic in origin. The volcanoes and their eroded remnants are the visible magmatic expression of the Cascadia subduction zone, where the offshore Juan de Fuca tectonic plate is subducted beneath North America.
Why are they called the Cascade Mountains?
The American explorers Meriwether Lewis and William Clark, on their expedition to the northwest in 1806, passed through the range in the 4,000-foot- (1,219-metre-) deep Columbia River Gorge on the Washington-Oregon border. The range was named for the great cascades found near the gorge.
Which Cascade volcano will erupt next?
Scientists are forecasting that the Pacific Northwest’s most active volcano will erupt sometime between 2020 and 2024. The volcano isn’t one you’ll see driving along the Cascade Range, instead you’d have to look 1.5 miles deep in the ocean to find it.
Which Cascade Range volcano erupted most recently?
Mount St. Helens
Two most recent were Lassen Peak in 1914 to 1921 and a major eruption of Mount St. Helens in 1980. It is also the site of Canada’s most recent major eruption about 2,350 years ago at the Mount Meager massif….List of volcanoes.

Is the Cascade Range volcanic?
Active volcanoes dominate the skyline of the Pacific Northwest. Cascade Range Volcanoes (Public domain.) The familiar snow-clad peaks of the Cascade Range are part of a 1,300 km (800 mi) chain of volcanoes, which extends from northern California to southern British Columbia.
Which Cascade volcano is most likely to erupt?
Given its restless nature, geologists say Mount St. Helens is the odds-on favorite to erupt next. But six other Cascade volcanoes have been active in the past 300 years, including steam eruptions at Glacier Peak and Mount Rainier and a 1915 blast at Mount Lassen, in California, that destroyed nearby ranches.
What is the most active volcano in the Cascade Range?
Mount St. Helens was formed during four eruptive stages beginning about 275,000 years ago and has been the most active volcano in the Cascade Range during theHolocene. Prior to about 12,800 years ago, tephra, lava domes, and pyroclastic flows were erupted, forming the older St.
What are the 2 most seismically active volcanoes in the Cascade Range?
By volume, the two largest Cascade volcanoes are the broad shields of Medicine Lake Volcano and Newberry Volcano, which are about 145 cubic miles (600 km3) and 108 cubic miles (450 km3) respectively. Glacier Peak is the only Cascade volcano that is made exclusively of dacite.
What are some interesting facts about the Cascade Range?
