Glacier Peak

(stratovolcano 3213 m / 10,541 ft)
Glacier Peak is a stratovolcano in northern Washington and the most remote of the Cascade volcanoes. Its name comes from the 11 glaciers on its flanks.
Although it reaches more than 10,000 feet elevation, the volcanic edifice is only 500-1000 m high, because the volcano's b... [más info]

Goat Rocks

(stratovolcano 2494 m / 8,182 ft)
Goat Rocks is the center a deeply eroded, glaciated volcanic center of a volcanic field 30 km (18 miles) north of Mount Adams, Washnington, USA. [más info]

Indian Heaven

(shield volcanoes 1806 m / 5,925 ft)
Indian Heaven volcano is a volcanic field 30 km halfway between Mt St. Helens and Mount Adams volcano, Washington, USA. It contains several low overlapping basaltic shield volcanoes and more than 50 flank vents with spatter cones primarily oriented along a N-S line.

Mount Adams

(stratovolcano 3742 m / 12,277 ft)
Mt Adams stratovolcano 50 km east of Mt St Helens volcano is the by volume second largest volcano of the Cascades Range, after Mt. Shasta.
Mount Adams is the center of a 200 km3 volcanic field. The andesitic-dacitic volcano was built by several overlapping cones. It is elon... [más info]

Mount Baker

Ear... [más info]

Mount Rainier

(stratovolcano 4329 m / 14,409 ft)
Mount Rainier, the highest peak in the Cascade Range, is located 87 km SE of Seattle and forms a majestic backdrop to the landscape of the region. The volcano is covered by 26 main glaciers, and melting of glacial ice by a future eruption causing lahars are a significant hazard f... [más info]

Mount St. Helens

(stratovolcano 2549 m / 8,363 ft)
Mount St Helens volcano hardly needs introduction. In its spectacular eruption in 1980, it placed itself deep into collective memory, in particular within the NW states of the USA. Prior to this eruption and its gradual reawakening, little attention had been given to the volcanic... [más info]

Signal Peak

(shield volcano 1555 m / 5,102 ft)
Signal Peak is the eroded remnant of a small andesitic stratovolcano overlying the southern part of the basaltic shield of the Lincoln Plateau.
Together with still active Mount Adams volcano to the west and the older Simcoe volcanic field of cinder cones to the east, it is ... [más info]

Simcoe

(volcanic field )
Simco volcanic field is a N-S aligned cluster of 24 monogenetic cinder cones. It is located E and SE of Mt Adams, Washington, California, near the town of Goldendale.
Associated is the younger basaltic Lincoln Plateau with Signal Peak at the western end of the field and ea... [más info]
