Roadside Geology of Washington (Roadside Geology Series) (Roadside Geology Series)
Product Review "Through the Roadside geology of Washington . . . I've started to make sense of . . . the natural features of our state . . . from the vast volcanic flows that formed the Columbia Plateau . . . to the 1980 eruption of Mount St. Helens." --Kristin Jackson, Seattle Times Product Description The geology of Washington is a story of islands--micro-continents--coming in from the sea. Two hundred million years ago most of Washington consisted of two large islands, each one a scrap of continent, lying somewhere in the vastness of the Pacific Ocean. One after the other they docked onto the North American continent, each adding its distinctive bit to the complex geologic and geographic mosaic of western North America. Reader Reviews Let's say you have a craving for geology, which is one of the hottest subjects on the planet (you know, molten rock and such). Let's say you want to drive a particular route through Washington State. This book is organized by route (just like the other books in the series) so you can have an expert's explanation of what geologic features you are looking at and how they were formed. Imagine a time of massive flooding when glacial Lake Missoula burst out of the ice dam and drenched most of Eastern Washington with 500 cubic miles of water more than thirty times. You can easily find the evidence today with the help of this book. Imagine a time when the northern end of Puget Sound was blocked by glacial ice, the level of water in the sound was about 100 feet higher than today, and all the rivers draining into the South Sound were dammed up and forced to escape to the South, through modern-day Black Lake and down the Chehalis River Valley. Some people worry about Mt. Rainier erupting again, which of course it will. But imagine the numerous and relatively recent mudflows off Mt Rainier which were not even associated with an eruption. Some of these mudflows contained up to a cubic mile of material with the consistency of liquid bricks. The inundated areas are now inhabited by hundreds of thousands of people. All you folks in Sumner and Orting, good luck in the next one! Once I wanted to be a Geologist, but the projects took too long to complete. If you have this book, at least the explanation is fast and easy to understand for the non-geologist such as myself. All the books in this series are fun to read when traveling through the subject areas. Thanks, Steve Willie, Olympia, WA Comment | | (Report this)
