There Must Have Been an Angel: The Cross-country Odyssey from Badwater, Death Valley, to the Summit of Mount Whitney (Paperback) (ISBN-13: 9781463765118)

Lee Bergthold has spent the past 50 years trekking across remote regions of the desert and mountain Southwest United States. He travels solo, and with hand-picked, pre-trained companions who specialize in survival techniques. The author still maintains a rigorous schedule of 80 to 100 days a year in the backcountry, roaming isolated regions where few others dare to tread: Northern Nevada to the Mexican Border; Utah to the Sierra Nevadas...all points between. Bergthold's forays range from 10 days to 35 days, specifically when exploring Donner Party migration routes. Bergthold is authoring three other books: To Walk Away From Battle Mountain; The Night of the Triangle; and The Hastings Cutoff. Bergthold is a former Marine (Korean War) and is professor of Photography/Photojournalism at Antelope Valley College, where he also conducts survival seminars.
