Description
Until about 200 million years ago, the western
margin of North America lay to the east, along the
present Idaho border, and a broad coastal plain
spread westward into Oregon. The rest of the state
was ocean floor. Then the continent began moving
slowly westward away from Europe and the floor of
the Pacific Ocean began sliding beneath the western
edge. That is what created Oregon, and this book
tells how it happened.
Professional geologists write and edit the "Roadside
Geology" books for people who are not geologists but
would like to learn something about the rocks and
landforms around them.Each book begins with an
introductory chapter that briefly reviews the rocks and
landscapes of its state. The remaining chapters provide
a detailed discussion of state regions and end with a
series of road guides.
