Since the early 1900s, Pendleton Woolen Mills has paid tribute to American’s National Parks with a collection of distinctive park blankets. The Glacier Park National Park Blanket was one of the first. The historic markings and colors date back to the frontier trading posts. The stripes on the blanket were indicative of the value of the blanket. Each color pattern represents a different National Park. These are made in the USA and will be in your family for generations to come. Pick your favorite park and color pattern and start your own collection!
