In July of 1901 my father and mother left St. Paul, Minnesota, on the second leg of their honeymoon for the Lewis and Clark Forest Reserve, which is known today as Glacier National Park. My father, Dr. Walter Bradford Cannon, was a young instructor in the Department of Physiology of the Harvard Medical School, and my mother, Cornelia James Cannon, a recent graduate of Radcliffe College with the class of 1899. They had been married some three weeks before and had with their usual energy and sense of adventure paddled a birch-bark canoe down the historic St. Croix River and then for sixty miles along the broad Mississippi between its impressive bluffs. As my father wrote in his autobiography, The Way of an Investigator, they were twice reported as Indians and occasionally regarded as harvest hands looking for jobs. Then, sunburned a dark brown and toughened by the hard work of propelling their heavily laden craft and making and breaking camp every day, they were ready for fresh adventure. So they set their faces west and boarded a train for Montana.
