Body
The landscape history of the last 150 years was reconstructed by the examination of the sedimentary record of eight small lakes in the northern range of Yellowstone National Park. The purpose was to determine if changes could be attributed to grazing and other activities of elk, bison, and other large ungulates. Sediment core samples were taken from the deepest part of each lake. Samples were examined for pollen content, diatoms, lead-210 dating and geochemistry.
