Early park accounts report significant soil erosion with the build-up of the elk herd, and comment that the original nature of the topsoil mantle would never be known. Observations of surface rock pediments and inside-outside exclosure studies of soil erosion show increased levels on the outside just since exclosure construction. Streambank research and lichenometric studies show elevated bank sloughing in the northern range where bank vegetation has been eliminated.

Keywords: topsoil; surface rock pediments; erosion; exclosure studies; lichenometry; streambank sloughing
