The Boring Lava Field is a Plio-Pleistocene volcanic field with cinder
cones, small shield volcanoes, and lava flows in the northern Willamette
Valley of the U.S. state of Oregon and adjacent southwest Washington
state. The zone became active about 2.7 million years ago, with long
periods of eruptive activity interspersed with quiescence. Its last
eruptions took place about 57,000 years ago; individual volcanic vents
are considered extinct, but the field itself is not. The volcanic field
covers an area of about 1,500 square miles (3,900 km2) and has a total
volume of 2.4 cubic miles (10 km3). The highest elevation of the field
is at Larch Mountain, which reaches a height of 4,055 feet (1,236 m).
The Portland metropolitan area, including suburbs, is one of the few
places in the continental United States to have extinct volcanoes within
a city's limits. The probability of future eruptions affecting the
Portland metropolitan area is very low.

Pardon me, if I'm sentimental When we say goodbye, Don't be
angry with me should I cry. When you're gone, yet I'll dream A little
dream as years go by… Now and then there's a fool such as I.
