GEOLOGY OF THE PACIFIC NORTHWEST! Part 2: Exotic Terranes!

Geologic history of the Pacific Northwest!
This is the second in a series of 4 videos, each one set up as a virtual field trip through the various rocks and landscapes of the Pacific Northwest- working through its past billion years of geologic history! Today, we'll find out what happened when the tectonic setting of the proto-Pacific Northwest switched from being a passive margin to active subduction... and the addition of exotic terranes! You could say that there's a fair bit of the Pacific Northwest that is quite exotic :-)

Thanks for watching!
