1968 Map of Mulligan Lake

About this map

Beltrami Island State Forest dominates this northern Minnesota landscape, where the shifting boundaries of Roseau, Beltrami, and Lake of the Woods counties meet. The terrain is defined by a vast network of wetlands and conservation lands, including the Red Lake Indian Reservation and the Red Lake State Wildlife Management Area. A system of Jeep Trails provides the primary overland access through these marshy reaches, connecting small industrial sites like a Gravel Pit to the surrounding wilderness. The hydrology of the region is centered on the slow-moving Roseau River, which winds eastward toward Mulligan Lake, while Hansen Creek drains the northern section of the forest. This survey reflects a period when this remote borderland remained largely focused on state-managed natural resources and indigenous land rights.
