The Columbia River Gorge National Scenic Area encompasses 292,500 acres in an 85-mile run of the Columbia River, beginning at the Sandy River about 17 miles east of Portland, Oregon, extending just beyond the Deschutes River to the east. It is bounded on either side of the river by more than fifty peaks and high points, giving it a fjord-like appearance. This book provides a comprehensive introduction to the natural history of the Columbia River Gorge, focusing on its geology, hydrology, geomorphology, weather, plants, animals and people. The beginning of each chapter includes recommended reading, and additional information and references are included throughout the text and in chapter notes. The book is intended to be supplemented with use of the field guides for those who want to learn more about the Gorge’s geology and how to identify its birds, plants and animals. The text helps readers understand how the Gorge was formed, what makes it special, and how people have lived there over time.
