 In the late 1960s, Dr. James Reddick, a Seattle dentist and experienced mountaineer, took his 12-year-old daughter, Sharon, and 11-year-old son, David, on a hike up the steep slopes of Mount Rainier one Memorial Day weekend to teach them the joy of mountain hiking. A sudden snowstorm with hurricane force winds and thick, wet sheets of snow trapped Reddick and his children against the side of the mountain.
