Details for: Hood
Sharp-topped Mount Hood, Oregon's highest peak, rises above the Lolo Pass area on its NW side. Hood is a prominent landmark on both sides of the Columbia River. The summit of the glacially eroded volcano contains several lava domes. At least four major eruptive periods have occurred during the past 15,000 years, the last of which was only about 170-220 years ago. Minor 19th century eruptions were witnessed from Oregon's largest city, Portland. Photo by Richard Fiske (Smithsonian Institution).

Location: Mount Hood (View Details at MaGa DB)
Description: Mount Hood is a potentially active stratovolcano in the Cascade Volcanic Arc of northern Oregon. It was formed by a subduction zone on the Pacific coast and rests in the Pacific Northwest region of the United States.The glaciers on the mountain's upper slopes may be a source of potentially dangerous lahars when the mountain next erupts.
