Colorado has been inhabited by people for thousands of years from the earliest Ancient Pueblo peoples to more recent native peoples such as those of the Apache Nation, the Algonquian-speaking Arapaho and Cheyenne, and the Numic-speaking Comanche, Shoshone, and Ute. The book examines the history and culture of these peoples and how they were shaped by the state's geography and climate. It also looks at how native peoples were affected by the arrival of the Spanish and later by widespread Anglo settlement.
