Dreaming of Sheep in Navajo Country (2009) offers a fresh interpretation of the history of the government's failed policy to preserve grazing lands by eradicating livestock on the Navajo reservation during the 1930s, with particular focus on women, the primary owners and tenders of the animals. Winner of the Hal Rothman Award, the Norris and Carol Hundley Award, and the Caroline Bancroft Honor Book Award, among others.
Land of Plenty (1995), a social and labor history, narrates the experiences of the pejoratively named "Okies," who were lured to and labored in Arizona's cotton fields during the Great Depression. Now out of print, this book won the Angie Debo prize for best book on the American Southwest published by the University of Oklahoma Press.
My scholarly essays have dealt with the so-called Okie migration, agricultural labor, Navajo environmental history, and gender.
My short journal writings focus primarily on environmental controversies, environmental justice, and public history.
