The Lewis and Clark Expedition was written on rivers. Moving west of the Mississippi, the expedition travelled along the Missouri, Snake, Yellowstone, Columbia and other smaller rivers during its 1804-1806 transcontinental exploration. This book explores how Western rivers travelled on by the Lewis and Clark expedition changed during two centuries since their voyage. Many changes were born from an attitude (no longer prevalent) that controlling nature was humans' right and duty. This attitude led to the construction of massive dams and the creation of 'engineered' rivers. How did these changes impact people and their attitudes? Rivers of Change lets conversations, research and odd historical tales tell the story. To succeed in their mission, Lewis and Clark solicited local information and worked in concert with environments they moved through. It's time to relearn those lessons if we want to preserve the health of this country's rivers. Rivers of Change entertains as it tells how. At the dawn of U.S. history, the Lewis and Clark expedition transformed Western geography from an unknown myth into documented reality. It's time to celebrate the achievements of this band of explorers, and to rethink how we manage rivers - the lifeblood of our continent. It's also time to enjoy a good book!
