Its fires help give to the Interior West a peculiar character, fundamental both to its natural and human histories. While a general aridity unites the region, defined here as the states of Nevada, Utah, and western Colorado, its fires illuminate the ways its various parts show  profoundly different landscapes, biotas, and human settlement experiences. In this book, fire historian Stephen J. Pyne explains the relevance of the region to the national fire scene. The Interior West offered the first scientific inquiry into landscape fire in the United States, including a map of Utah burns published in 1878 as part of John Wesley Powell’s arid lands report. Then its significance faded and by the 20th century, the region had become the hole in the national donut of fire management. Pyne discusses the region’s more recent return to prominence due to fires along its front ranges; to invasive species, both exotics like cheatgrass and unleashed natives like mountain pine beetle; and to its fatality fires, notably at South Canyon in 1994. The Interior West shows the variety of fire issues in the region and their significance to the country overall through thoughtful framing and lively essays.
