Powell Butte Cinder Cone "Climb A Volcano!" The coordinates
will
take you to the summit of Powell Butte a Plio-Pleistocene
cinder
cone of the Boring Lavas. On a clear day you can spot Mount
St.
Helens, Mount Hood, Mount Adams and Mount Jefferson. I recommend
parking in the main lot (access from SE 162/Powell)
POWELL BUTTE:
Powell Butte is crowned by an open meadow area ringed by forest and
is Portland's second-largest park after Forest Park. The meadows of
grass, which are sprinkled with apple, pear and walnut trees; and
picnic tables are sporadically situated, offering great locales for
a midday lunch. With nine miles of trails winding through 608 acres
of rolling grasslands, Powell Butte Nature Park is the perfect
inner-city getaway. From the gravel parking lot you can choose from
a variety of trails, but be sure to read the signs--some allow for
bikes and horseback riding. The paths are well-maintained, and some
are even paved with new blacktop. Powell Butte is also home to
several species of wildlife, including birds, raccoons, foxes,
coyotes and deer. This butte is also a major storage facility for
Portland's water supply the water tanks are buried beneath the
grassy meadows near the main parking area.
BUTTE GEOLOGY:
Powell Butte is an extinct volcanic cinder cone, it is one of three
such cones inside the city of Portland, the others being Rocky
Butte and Mount Tabor. Rock outcrops are hard to find on powell
butte but none the less it is part of the boring lava field, an
area of extinct volcanoes which lies just to the southeast of the
most dense cluster of lava vents which includes at least 32 and
possibly 50 cinder cones and small shield volcanoes. The zone
became active at least 2.7 million years ago, and has been extinct
for about 300,000 years. 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; Bend, Oregon is
another.
