Beyond the Hundredth Meridian: John Wesley Powell and the Second Opening of the West

Wallace Stegner reconstructs the career of John Wesley Powell, the one-armed Civil War veteran who led the first scientific expedition through the Grand Canyon. The narrative moves from the 1869 river descent into a broader analysis of Powell’s work as a cartographer and director of the U.S. Geological Survey. Stegner details Powell’s unsuccessful attempt to change federal land laws, specifically his argument that the arid West could not support traditional 160-acre homesteading because of its scarce water resources and distinctive topographical limits.

Students of environmental history and resource management read this book to understand the disconnect between political expansionism and ecological reality. It provides a technical look at how bureaucratic structures formed around the management of public lands and irrigation. Readers gain a clear perspective on why the western United States developed its current patterns of water rights and urban growth. They finish the text with a functional knowledge of the hydrological constraints that define the American desert and the failure of early policy to adapt to those scientific facts.
