Cascade Volcanoes

Mt. St. Helens is a stratovolcano part of a group of volcanoes called The Ring of Fire. These are created from the convergence/subduction between the Juan De Fuca plate and the North American plates. Its most common type of eruption is intermediate eruptions, which is what the composition was in its most recent eruption. Mt. St. Helens most recently erupted on May 18, 1980. An earthquake right under the mountain caused an enormous landslide/avalanche going close to 150 mph. A huge hazard from…

can reach anywhere from 4,000 to 5,000 feet. Modoc Plateau is bordered by Medicine Lake Highlands (part of the Cascade Range) on the east and Warner Mountains on the west. See the map for a better idea of its location. . Modoc Plateau has an interesting geological history, one similar to the Hawaiian islands. Unlike other volcanoes, the volcanic eruptions produced by shield volcanoes are generally small-scale and produce trickling, slow-moving lava. The slow-moving lava hardened over time to…

eighty-five miles of highway. Mount Saint Helens had been dormant for the past one hundred twenty-three years. The volcano was also a strato-volcano. The volcano is part of the Cascade Volcanic Arc. A volcanic arc is a chain of volcanos formed over a subduction plate. The Cascade Volcanic Arc is a major range of volcanoes stretching all the way from British,…

Mount St. Helen's is an active stratovolcano in the Cascade Range in Skamania County, Washington and is part of the Ring of Fire centered around the Pacific Ocean. Mount St. Helen's was created when the oceanic Jean de Fuca plate subducted beneath the North American Plate and has a long history of eruptive periods followed lengthy dormancies. Her volcanic activity was marked by thousands of years of lava and pyroclastic flows only to fall silent and then reawaken to begin her destructive cycle…

A Oregon has a marvelous agriculture including many crops and animals. Oregon has two main crops; hazelnuts and pears. Hazelnuts are the state nut. Hazelnuts are high in protein and fiber. 95% of America’s hazelnuts are produced in Oregon. Another important crop is the pear, the state’s fruit. Oregon is 2nd in the nation for pear production. Cows are an important part of Oregon’s agriculture. Oregon is in the top five for milk quality. Cows produce 6.5 gallons of milk everyday! Milk is also the…
