Mount Adams, one of the largest volcanoes in the
Cascade Range, dominates the Mount Adams volcanic
field in Skamania, Yakima, Klickitat, and Lewis
counties and the Yakima Indian Reservation of south-central Washington.
The nearby Indian Heaven and
Simcoe Mountains volcanic fields lie west and
southeast, respectively, of the 1,250 square kilometers (500 square miles)
Adams field.
Even though Mount Adams has
been less active during the past few thousand years
than neighboring Mounts St. Helens, Rainier, and Hood,
it assuredly will erupt again. Future eruptions will
probably occur more frequently from vents on the
summit and upper flanks of Mount Adams than from vents
scattered in the volcanic fields beyond. Large
landslides and lahars that need not be related to
eruptions probably pose the most destructive, far-
reaching hazard of Mount Adams. The purpose of these
maps and booklet is to (1) describe the kinds of
hazardous geologic events that will likely occur in
the future at Mount Adams and at other volcanoes in
the region, (2) outline the areas that will most
likely be affected by these events, and (3) recommend
actions that individuals and government agencies can
take to protect lives and property.
