Marc S. Hendrix is a Professor of Geology at the University of Montana in Missoula, Montana. Growing up in Gettysburg, Pennsylvania, he developed an early love of geology in the 1970s while working as a field assistant for his father, a biology professor at Gettysburg College. He earned a bachelor's degree in geology from Wittenberg University in Springfield Ohio in 1985, a master's degree in geology and geophysics from the University of Wisconsin-Madison in 1987 and a Ph.D. in applied earth sciences in 1992 from Stanford University, where he conducted research on the geologic record of mountain building and ancient climate in western China. As a postdoctoral researcher at Stanford, he analyzed the geologic history of Mongolia. In 1994 Dr. Hendrix joined the faculty at the University of Montana where he has developed a field-based research program focused on the geology of the northern Rocky Mountains. He and his students have published a variety of technical papers on the geology of North America, Asia and Africa, and in 2011 he authored and illustrated GEOLOGY UNDERFOOT IN YELLOWSTONE COUNTRY. Dr. Hendrix has served as an expert witness and consultant in the field of geology, and he continues to travel broadly to conduct geologic research. He lives in Missoula with his wife and two sons.
