Mt. Hood, in northern Oregon, is one of the most beautiful and symmetrical stratovolcanoes in the Cascades. At 11,249 ft. (3,429 m), it is the tallest mountain in Oregon. It is also considered to be one of those most likely to erupt in the next few decades or centuries, with nearby Portland at risk for lahars and ash falls. As noted in previous posts, these volcano pictures resulted from a flight to Seattle on an extraordinarily clear day in 2003.
