Volcano Monte Hood

O pico mais alto do Oregon ergue-se a cerca de 80 km de Portland e o USGS classifica-o como vulcão de «ameaça muito elevada». As suas últimas erupções significativas, no final do século XVIII, enviaram lahares pelo rio Sandy até ao Columbia; hoje os seus glaciares abastecem de água a região, pistas de esqui cobrem as suas encostas e pequenos enxames sísmicos sob ele lembram regularmente que continua ativo.
