The area was a bustling fur trading station since the 1700s, and the French Canadian Voyageurs termed the settled village ‘Grand Marais’ which is French for "Great Marsh", referring to a marsh that, in early fur-trading times, was 20 acres (8.1 ha) or less in area, nearly at the level of Lake Superior, and situated at the head of the little bay and harbor that led to the settlement of the village there. Another small bay on the east, less protected from storms, is separated from the harbor by a slight projecting point and a short beach. Also, ‘Grand Marais’ also may mean "sheltered water area," as the harbor has natural breakwall rock outcroppings, providing for a natural safe harbor for early Lake Superior explorers.
