From the interactive clockwork world of geology, tides, Northwest weather, and snow, to the hidden roles of dirt, stream life, and mosses and lichens, William Dietrich explores the natural splendors of the Pacific Northwest. His topics include alder and cedar; jellyfish, geoducks, crabs, and killer whales; mosquitoes and spiders; gulls, crows, raccoons, possums, deer, and cougars. This book is intended as a primer for people who are curious about the environment they live in and the pressures upon it. Dietrich has unearthed fascinating and unexpected facts about his subjects, and expresses complex information in clear and vivid language. He asks intriguing questions and makes good use of interviews with Northwest scientists and experts to convey current and historic attitudes and economic realities, and to consider where we go from here.
