“Becoming America’s Ski City” explores how skiers remolded the political, economic, cultural, and environmental landscape of Utah’s Wasatch Front, transforming the region’s valley cities and mountain forests into a more unified yet contested space over the course of the twentieth century. This process of incorporation centered on Salt Lake City. In particular, the exigencies and experiences of skiing pushed Salt Lake Citians not only to recognize the ecological ties between slope and city but also to build new connections. These links included watershed regulations, land purchases, avalanche management, investment, federal boosterism, marketing campaigns, urban planning, wilderness legislation, and the Olympic movement. Skiing also represented a larger attempt to Americanize Utah and its predominantly Mormon population. By shifting attention away from popular images of the state as an insular desert, boosters attempted to build a stronger economy rooted in tourism that placed Utah more firmly within mainstream American culture. Their partial success points to the ways in which skiing eroded boundaries between city and periphery as well as state and nation. This process sheds light on the blurred dichotomies that defined modern American life within and beyond Utah— work and leisure, city and wilderness, region and nation—and the material and social changes that they molded.
