Cooking Hillside, Yellowstone National Park, Wyoming - wy035 Additional Site Information John C. King and William C. Evans Purpose of Collection: Geomorphology/Geology - volcanology Detrend method: Negative exponontial or linear regression with negative or 0 slope Cores are stored at: Samples are archived with Lone Pine Research, 2604 Westridge Drive, Bozeman, MT, 59715, 406-579-8529 Reference: Publication Pending. Contact: William C. Evans, U.S. Geological Survey, 345 Middlefield Road M/S 434, Menlo Park, CA 94025, 650-329-4514 Notes: This project examines temporal patterns of atmospheric 14C depletion due to magmatic CO2 gas emissions. The tree-ring collection site is located at a thermal feature in Yellowstone National Park. Sample cross-dating was confirmed using both published and unpublished tree-ring chronologies from the region. Individual annual rings were excerpted from additional core samples for radiocarbon analyses.
