Assistant Professor



I am an environmental historian of the modern American West. My first book, Colorado Powder Keg: Ski Resorts and the Environmental Movement (University Press of Kansas, 2012), discussed the history of Colorado’s ski industry and the emergence of the postindustrial West, where mountains became more valuable as ski resorts than as rangelands. The book was awarded the International Ski History Association's Ullr Award, and was runner up for the Western Writers of America's Spur Award in 2013.

I am currently writing my second book, “The Mountains are Calling Tourists and the Unmaking of Yosemite National Park,” examining the park’s history through visitors’ own experiences, as well as the environmental costs of tourism.

Additionally, I am the co-book review editor for Environmental History and the co-series editor for the University of Oklahoma Press’ Environment in Modern North America book series.
