This dissertation examines the environmental history of a unique corner of the American West. The Palouse, an expanse of rolling hills in southeastern Washington and northern Idaho, has been intensively cropped, mostly in wheat and other small grains, since the late nineteenth century. Because of this activity and the region's topography, climate, and soil types, massive amounts of soil have eroded from nearly every acre of farmland since Euro-American settlement. The result has been a steady depletion of soil fertility and the deterioration of surface water quality. This project seeks to uncover why this situation persisted through the twentieth century. Based on evidence gleaned from the archival material of regional experts and farmers, numerous government reports, and local newspapers, farmers have been reluctant to change practices to reduce erosion for several reasons: many early settlers believed that the topsoil was inexhaustible; financial concerns drew farmers' attention away from soil conservation; technological improvements increased yields and made some farmers think erosion was tolerable; ineffective government programs; and an absence of land stewardship. The post-World War II proliferation of farm chemicals complicated the environmental picture. Powerful new fertilizers, herbicides, and pesticides vastly improved yields of all crops, but they also gave farmers another excuse to avoid soil conservation. The higher returns implied that erosion had no short-term impact on productivity. This fallacy persisted for decades while erosion continued to deplete the soil. The environmental movement of the 1970s and 1980s spawned new legislation designed to reduce erosion and improve water quality. But state and federal laws aimed at coercing farmers into adopting conservation practices were not thoroughly implemented at the local level. Farmer opposition to land use restrictions and an ongoing lack of stewardship values in addition to financial pressures, derailed legislative remedies and perpetuated erosion and abysmal water quality. From the earliest days of Palouse settlement, farmers were raised on an ethos of independence and the value of unlimited growth. Although this spirit allowed intensive agriculture to thrive, it simultaneously threatened long-term sustainability and irrevocably altered an entire ecosystem.
