Oregon’s Mt. Hood at 3700 m height is located just south of Mt. St. Helens. The latter one erupted in May 1980 with medium intensity. Both are typical stratovolcanoes of the Cascade Range. Mt. Hood erupted back in 1853. Since then the glaciated giant is dormant. The subducted ocean off the coast changes the volcanoes magma into an explosive chemical cocktail including wet sediments of the Steinmann-Trinity. Once basaltic magmas are transformed into high explosive lavas, called ryolithe and andesite. Mt. Hood is composed out of these high explosive lavas.
