The cryptodome on the side of Mount St. Helens was approximately 1,300 feet long, 65 feet wide, and 40 feet high. It was a large bulge caused by rising magma beneath the volcano before its 1980 eruption.
Mount St. Helens was formed by volcanic eruptions and flows over a long period of time.The Cascade Mountains were formed by the collision of the Juan de Fuca Plate with the North American plate. Lava was forced upward to create volcanoes such as Mount Adams and Mount St. Helens.The modern summit domes were the Kalama dome, formed between 1490 and 1647, and the Goat Rocks dome, formed between 1800 and 1857. These raised the mountain to its highest modern height. In 1980, the Goat Rocks dome was obliterated by the avalanche and eruption.A new dome, as well as a surrounding glacier, have formed within the horseshoe-shaped crater. But to reach its pre-1980 size will require many more lava flows over a period of hundreds of years.
Mount Vesuvius formed approximately 25,000 years ago.
Yes, the United States has several active volcanoes, including in Hawaii (Kilauea, Mauna Loa), Alaska (Mount Redoubt, Mount St. Augustine), and the Cascade Range (Mount St. Helens, Mount Rainier). Hawaii and Alaska have the most volcanic activity in the U.S.
I don't know who was the first person to climb Mt St. Helens, but below is a good site to visit regarding the mountain: http://www.mshinstitute.org/ It was Thomas J. Dryer
