This work investigates the historical paradox wherein the creation of American national parks necessitated the systematic removal and exclusion of indigenous populations from their ancestral lands. Mark David Spence, a historian specializing in the American West, utilizes archival records and federal policy documents to argue that the 'wilderness ideal' was a constructed concept used to justify the displacement of native peoples. By situating park development within the broader context of the reservation era, the author demonstrates how preservationist policies functioned as a mechanism of colonial control.

Scholars and historians frequently cite this work as a foundational text for understanding the intersection of environmental policy and indigenous rights. Readers often note the rigorous archival research and the clarity with which the author challenges traditional narratives regarding the origins of the American national park system.
