Geologic Overview of a Bison-Carcass Site at Norris Geyser Basin, March 2004

Heasler Hank, Yellowstone National Park

This Yellowstone National Park report describes the conditions that apparently caused the death of five bison near the Norris Geyser Basin. The bison appear to have died from hydrogen sulfide and/or carbon dioxide emitted from nearby gas vents. This PDF file contains text, data, and photographs that explain the Park scientist's findings.
