Mt.Hood, Oregon

Having passed Mt.Rainier, Mt.St.Helens and Mt.Adams in Washington state, Mount Hood stands proud, just over the border in the State of Oregon.

The chances of this potentially active volcano erupting in the next 30 years are put at 3-7% by the United States Geological Survey.

Its last major eruption occurred only a few minutes ago, geologically-speaking, in 1782.
