Mount Hood, seen here from the north across the Columbia River Gorge, rises above low hills of older volcanic rocks. Located only 75 km ENE of Portland, Mount Hood is near communities, infrastructure, and transportation routes, posing risk from eruptive activity and debris flows. The morphology of the summit area has been modified by flank collapse events that formed debris avalanches.
