Landforms of the Pacific Northwest
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
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.
Small: 1:1.25 million, 1” = approximately 20 miles
Medium: 1:1 million, 1” = approximately 16 miles
Large: 1:750,000, 1” = approximately 12 miles
