Mount Hood, a dormant stratovolcano, reflected in the waters of Trillium Lake, Oregon, United States. At 11,249 feet (3,429 metres), Mount Hood is the highest mountain in Oregon and the fourth-highest in the Cascade Range. It is considered an active volcano, but no major eruptive events have been catalogued since systematic record keeping began in the 1820s. Photo credit: Oregon's Mt. Hood Territory |
