Landforms of the Pacific Northwest - Fine Art Print Map
The Pacific Northwest’s signature volcanoes are almost perfectly aligned
north to south for over 500 miles from Mt. Baker to Mt. Shasta— surface
evidence of the subducting Juan de Fuca Tectonic Plate’s shape. The
current peaks are, geologically speaking, brand-new and active, their
earlier equivalents are the worn-down western Cascades; the Northern
Cascades and Canadian Coast Ranges are are more or less unrelated).
Flood basalts are the signature landform of the interior Pacific
Northwest. The smooth melted shapes of Yellowstone reveal the overriding
Pacific Plate’s current position over the “hot spot” that has left a
400 mile (and 17 million year) long path from what is now the Owyhee
Desert on the Oregon/Nevada/Idaho border. Those are just two of the many
landform stories apparent on the map.
Included on the map: all of
Washington, Oregon, Idaho, as well as a small portion of northern California,
with lots of British Columbia, Alberta, and Montana.
