WILLIAM PHILPOTT. Vacationland: Tourist and Environment in the Colorado High Country. University of Washington Press. Hardcover, 488 pages, $39.95,

William Philpott succeeds admirably in his ambitious goal of tying the rise of Colorado High Country tourism since World War II to “mass suburbanization, economic and geographic decentralization, and Sunbelt migration, as well as the deepening American dependence on automobiles” and a rising national environmental consciousness. The book won a Spur Award as Best Contemporary Nonfiction for 2014.
