National Geographic Map EARTHQUAKES VOLCANOES San Andreas Fault Mt. St. Helens

Description

Full-color fold-out map of the world showing the earth's dynamic crust — depicted as a patchwork of rigid plates riding on a churning, viscous mantle that spawns earthquakes and volcanoes.
This map opens to 18" x 23" and was published by the National Geographic Society in 1985.
On the reverse side there's a cut-away view of the geology of the northwestern United States, including the mountains of the Coast Range, Cascades, and Sierra Nevada, with detail on the San Andreas Fault and the eruption of Mount St. Helens.
This map was published as a supplement to the August 1985 issue of
