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 on Earth; in 1999 the ski area (on a subsidiary peak) recorded the world's greatest single-season snowfall: 1,140 in (29,000 mm).
Glacier Peak (northern Washington) — secluded and relatively inaccessible peak. Contrary to its name, its glacial cover is not that extensive. The volcano is surprisingly small in volume, and gets most of its height by having grown atop a nonvolcanic ridge.
High Cascades
Mount Rainier (southeast of
Tacoma, Washington) — highest peak in the Cascades, it dominates the surrounding landscape. There is no other higher peak northward until the Yukon-Alaska-BC border apex beyond the
Alsek River.
Mount St. Helens (southern Washington) — Erupted in 1980, leveling forests to the north of the mountain and sending ash across the northwest. The northern part of the mountain was destroyed in the blast (
1980 Mount St. Helens eruption).
Mount Adams (east of Mount St. Helens) — the second highest peak in Washington and third highest in the Cascade Range.
Mount Hood (northern
Oregon) — the highest peak in Oregon and arguably the most frequently climbed major peak in the Cascades.
Mount Jefferson (northcentral Oregon) — the second highest peak in Oregon.
Mount Washington (between Santiam and McKenzie passes) — a highly eroded shield volcano.[3]
Three Sisters (near the city of
Bend, Oregon) — South Sister is the highest and youngest, with a well-defined crater. Middle Sister is more pyramidal and eroded. North Sister is the oldest and has a crumbling rock pinnacle.
Newberry Volcano — isolated
caldera with two crater
lakes. Very variable lavas. Flows from here have reached the city of Bend.
Mount Bachelor (near Three Sisters) — a geologically young (less than 15,000 years) shield-to-stratovolcano which is now the site of a popular
ski resort. (
Mt. Bachelor ski area)
Mount Thielsen (east of Mount Bailey) — highly eroded volcano with a prominent spire, making it the Lightning Rod of the Cascades.
Mount Mazama (southern Oregon) — better known for its
Crater Lake, which is a
caldera formed by a catastrophic eruption which took out most of the summit roughly 6,900 years ago. Mount Mazama is estimated to have been about 11,000 ft (3,400 m) elevation prior to the blast.
Mount Scott (southern Oregon) — on the southeastern flank of Crater Lake. At 8,929 ft (2,722 m) elevation, this small stratovolcano is the highest peak in
Crater Lake National Park.
Mount Shasta (northern California) — second highest peak in the Cascades. Can be seen in the
Sacramento Valley as far as 140 mi (230 km) away, as it is a dominating feature of the region.
Lassen Peak (south of Mount Shasta) — southernmost volcano in the Cascades and the most easily climbed peak in the Cascades. It erupted from 1914 to 1921, and like Mount Shasta, it too can be seen in the Sacramento Valley, up to 120 mi (190 km) away. Lowest Peak because the Cascades extend from it.
Crater Lake National Park preserves the remains of
Mount Mazama, a large volcano that imploded thousands of years ago, forming a
caldera that was later filled with rain and ground water, later to be known as
Crater Lake.
