Susan Lamb was born in Palo Alto, Calif., but moved often with her family to such far-flung places such as Alaska and Germany. Drawn to the loveliness and the literature of the ancient world and intrigued by how closely pre-Socratic philosophers observed nature, she earned a bachelor's degree in classical civilization at the University of California, Santa Barbara, and a master's in Aegean and Anatolian prehistory at Bristol University in England. She 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. It was here 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. She now lives in Flagstaff, Ariz., with her husband, photographer Tom Bean. Her new book is "Channel Islands National Park, Second Edition."
