Sigurd Ferdinand Olson was an American writer, environmentalist, and advocate for the protection of wilderness. For more than thirty years, he served as a wilderness guide in the lakes and forests of the Quetico-Superior country of northern Minnesota and northwestern Ontario. He was known honorifically as the Bourgeois — a term the voyageurs of old used of their trusted leaders.

The Boundary Waters Canoe Area Wilderness comprises 1,090,000 acres (440,000 ha) of pristine forests, glacial lakes, and streams in the Superior National Forest. Located entirely within the U.S. state of Minnesota at the Boundary Waters, the wilderness area is under the administration of the United States Forest Service. Efforts to preserve the primitive landscape began in the 1900s and culminated in the Boundary Waters Canoe Area Wilderness Act of 1978. The area is a popular destination for canoeing, hiking, and fishing, and is the most visited wilderness in the United States.
