All of the known historic eruptions in the contiguous United States have been from Cascade volcanoes.
California Cascade Range Mountains
Cascade Range
- The Cascade Range is a mountainous region stretching
from northern California to British Columbia, Canada.
Beautiful to look at, the Cascade Range mountains offer inspiration and
beauty beyond compare.
The Cascades
are part of the Pacific Ring of Fire, the ring of volcanoes around the Pacific Ocean. All of the known historic eruptions in the contiguous United States have been from Cascade volcanoes. The last Cascade volcano to erupt in California was Lassen Peak, which erupted from 1914 to 1921. Lassen is the most southerly active volcano of the Cascade chain.
There are 7 national forests in the Cascade area in
California: Klamath National Forest, Lassen National Forest, Mendocino National Forest, Modoc National Forest, Plumas National Forest and Shasta-Trinity National Forest, as well as the Lava Beds National Monument. Shasta-Trinity National Forest is the largest National Forest in California
with 2.2-million acres encompassing five wilderness areas.
The forest spans 6 California counties that include
Humboldt, Modoc, Shasta, Siskiyou, Tehama and Trinity
counties. Lassen Volcanic National Park in the Lassen
National Forest was established in 1916 during the time the
mountain peak was erupting. The park includes the most extensive and active thermal areas in the United States outside Yellowstone National Park.
Where there are mountains, there are usually lakes! Over 6,000 miles of rivers
and streams feed from the mountains. Shasta Lake, the
largest man-made lake in California and houseboat capital of
the world, is located near Redding.
Bordering Oregon and Nevada north of the Sierra Nevada mountain range
and Central Valley of California, Mount Shasta
is a dormant volcano that may have erupted during the 18th Century.
