The upper Sandy River valley on the SW side of Mount Hood has been one of the primary channels for lahars associated with eruptions during the past 1800 years.  These late-stage eruptions originated from vents high on the SW flank of the volcano. Photo by Willie Scott, 1995 (U.S. Geological Survey).
