Volcano Mount Hood
Oregons höchster Gipfel liegt rund 80 km von Portland entfernt und wird vom USGS als Vulkan mit „sehr hoher Gefährdung“ eingestuft. Seine letzten größeren Ausbrüche Ende des 18. Jahrhunderts schickten Schlammströme den Sandy River hinab bis zum Columbia; heute speisen seine Gletscher die Wasserversorgung der Region, Skipisten bedecken seine Flanken, und kleine Erdbebenschwärme unter ihm erinnern regelmäßig daran, dass er noch aktiv ist.
