A visitor center run by the Washington State Parks is in Silver Lake, Washington, about 30 miles (48 km) west of Mount St. Helens. [100] Exhibits include a large model of the volcano, a seismograph, a theater program, and an outdoor natural trail. [100]
Located about 25 miles (40 km) north of Adams is Goat Rocks Wilderness and the heavily eroded ruins of a stratovolcano that is much older than Adams. Unlike Adams, the Goat Rocks volcano was periodically explosive and deposited ash 2.5 million years ago that later solidified into 2,100-foot (640 m) thick tuff layers. [34]
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 .
Twelve volcanoes in the arc are over 10,000 feet (3,000 m) in elevation, and the two highest, Mount Rainier and Mount Shasta, exceed 14,000 feet (4,300 m). By volume, the two largest Cascade volcanoes are the broad shields of Medicine Lake Volcano and Newberry Volcano, which are about 145 and 108 cubic miles (600 and 450 km 3) respectively.
Lone Butte is a 4,780 foot (1,460 m) tuya in the Indian Heaven volcanic field, Washington, United States. [1] [2] It is part of the Pacific Ring of Fire.Lone Butte last erupted during either the Hayden Creek glaciation 130,000-150,000 years ago (late Illinoian), or 70,000-90,000 years ago during the early Wisconsin glaciation.
