Hayden’s noteworthy achievements in science and conservation, however, are clouded by his views of indigenous people. Yellowstone Caldera Chronicles is a weekly column written by scientists and collaborators of the Yellowstone Volcano Observatory. This week's contribution is from Cole Messa, Ph.D. student, and Ken Sims, Professor of Geology and Geophysics, both at the University of Wyoming.
