Exotic Terrane

Geological discoveries in the Pacific Northwest.

"Students from high school to college will find themselves enthralled." **** Video Rating Guide for Libraries

The geological term "exotic terrane" refers to a group of rocks that has attached itself to a tectonic plate and migrated away from its place of origin. This fascinating program documents the latest geological discoveries in the Pacific Northwest, where fossils of an equatorial coral reef are being found along the ridges of Hells Canyon in eastern Oregon.

EXOTIC TERRANE contains the dramatic story of the scientists who pieced together the history of these rocks, and offers an explanation of the tectonic activity that makes such exotic displacements possible.
