In the pre-World War II era, Park Rangers patrolled Glacier National Park year-round, based out of ranger stations distributed unevenly around the park, protecting it from poachers and hunters as well as offering U.S.-Canadian border security and assistance to visitors. This book will be the first comprehensive, park-wide history of rangering, ranger life, dangers encountered by rangers performing their duties, and the men who were the Park Rangers in the early decades of Glacier National Park. The book will add to the knowledge of the rich cultural development of the park and its history through this unique examination of early rangers of Glacier National Park. The book contains dozens of historical photos of rangers at work, the ranger stations in which they worked, and the backcountry cabins in which they stayed when on patrol. Modern photos by the author illustrate the present-day environments in which rangers worked up to 100 and more years ago.
