Northwest Exposures
Product Description
A Geologic Story of the Northwest
by David Alt and Donald W. Hyndman
In geology, time is everything. And given enough time, almost anything can happen. “Northwest Exposures” traverses the region through geologic time, chronicling the events that have shaped the rocks and landforms.
The tale begins more than two billion years ago when an ancient continent split, creating oceanfront property in what is now western Idaho. Pacific islands mashed into that coastline, making large parts of Washington and Oregon. These events were followed by monstrous volcanic eruptions, catastrophic ice age floods, and mountains rising to an accompaniment of earthquakes. Written in an engaging prose and generously illustrated, “Northwest Exposures” is a must-read for anyone interested in the geologic history recorded in the landscape.
