The Rest Northwest provides a brief, easy-to-follow overview of the geologic processes that shaped the Northwest. One of the attractions of the Northwest is its varied terrain, from the volcanic Cascade Range to the flood-scoured scablands of eastern Washington and the eroded peaks of the northern Rockies. These vast differences are the result of a collision of the old and the new. The western edge of Idaho was once the edge of ancient North America; as eons passed, a jumble of islands, minicontinents, and sediment piled up against the old continental edge, gradually extending it west to the present coastline. Figuring out how and when these various land forms came together to create the Northwest took much geological detective work. Unlike many geology books that focus on rocks, The Rest Northwest emphasizes the human drama of geology. The narrative is sprinkled with firsthand accounts of people involved in the exciting geological discoveries made in recent years.
Hill Williams uses an informal conversational style to explain complex processes to a general readership. He enlivens the story of long-ago geologic events with fascinating asides on everything from enormous undersea tube worms to the Willamette meteorite, the largest ever found in the United States.
