The name Grand Marais (French: great marsh) is a reference to the large, shallow harbor. French explorers and fur traders from the time of New France used the word "marais" to mean "harbor of refuge" as well as "marsh."
A breakwater was later built that extends from the bay into Lake Superior. The Grand Marais Outer Range Light is at its end, and the Fresnel lens is still operative. It is one of only 70 such lenses that remain operational in the United States; 16 of these are in use on the Great Lakes, eight of which are in Michigan. Many controversies in the little town relate to the costs of dredging and breakwall-repair operations to keep the harbor functioning. See Grand Marais Harbor of Refuge Inner and Outer Lights.
