Abstract
This is a continuation of a project initiated in 1980 to characterize the major soils of Yellowstone National Park. It has entailed the integration of existing resource data, such as the Yellowstone National Park geologic map (U.S.G.S. 1972), surficial geological map (U.S.G.S. 1972) and the vegetative habitat map (Despain, 1980), with detailed soils characterization data.
