Susan Lamb served as a ranger-naturalist in the National Park Service for seven years; her last assignment was as Desert View District Ranger-Naturalist at Grand Canyon National Park. The Desert View District borders the Navajo Nation and her work there was to interpret the pre-Columbian and modern indigenous peoples of the Colorado Plateau, particularly the Hisatsinom and the Hopi. It was there that her love of nature and science, and her appreciation for diverse cultures converged. A chance assignment led to a freelance career writing interpretive natural and cultural histories and leading study tours in the West for the Smithsonian National Associates Program and other clients. Lamb's book is "White Sands National Park."
